I just found out Electrum can't handle "send to pubkey" inputs.
Ah! That’s the reason why rpc-explorer does not show balance for any of them! I was going to blame it…

I may be wrong as I haven't checked the Electrum source code
You are correct. The relevant code for the sweep function is here: https://github.com/spesmilo/electrum/blob/5f7388a475cd796c30caab688e7f8136a8c6ac27/electrum/wallet.py#L145-L174The sweep function calls the function find_utxos_for_privkey at line 171. This is defined at line 147, which then calls the function _append_utxos_to_inputs at line 149. This is then in turn defined at line 108, which looks for P2PK outputs.
This is not implemented across the wallet because it would involve every address in every wallet also having its pubkey queried for P2PK outputs, which would be an unnecessary increase in server load for a very rarely used type of script. Anyone still creating P2PK outputs is clearly doing so for a specific reason and not doing so via Electrum.
Electrum tries to sweep P2PK UTXOs from private keys in addition to P2PKH or P2SH UTXOs.
Does that mean the import private key feature does it too?I may be wrong as I haven't checked the Electrum source code and don't have any private key that controls a P2PK UTXO.

I can't test it either, but from above I read that Electrum tries to sweep P2PK UTXOs from private keys in addition to P2PKH or P2SH UTXOs.
Too bad there seems to be no SPV wallet solution?
I haven't found one. I'm curious which SPV wallets would check for P2PK-balances when you enter a private key, but I can't really test that.I'm currently searching the latest transactions that sent funds to a pubkey, to see how often it's still used. My guess is it's barely used, and considering I haven't missed this feature in years, it makes (some) sense they haven't implemented it.

Thank you for reminding me of importpubkey and importmulti, if that is the only solution with Bitcoin Core. I will need to do some more scripting to cram all pubkeys and addresses of my interest into a new Bitcoin Core watch-only wallet.
Too bad there seems to be no SPV wallet solution?

Does anyone have an idea or suggestion which wallet would be able to setup such a watch-only wallet that properly recognizes the P2PK transaction balances and additionally the later mostly P2PKH spam to the derived addresses?
Maybe with Bitcoin Core...
Yes, Bitcoin Core should do the trick. I found a post from achow101 from a few years ago. He explains how you have to import the public key into your watch only wallet for P2PK outputs to become visible. You can't import the address they are supposedly in because P2PK scripts don't have addresses. The public key should create the correct watch-only wallet. Maybe with Bitcoin Core...
The second is that importing an address will not give you the pubkey necessary for a P2PK output as those scripts don't have addresses. To add P2PK outputs as watchonly, you will need to import the public key directly.

Bitcoin Core can do this:Quote from: from Bitcoin Core Console
Code:
importpubkey "pubkey" ( "label" rescan )
Adds a public key (in hex) that can be watched as if it were in your wallet but cannot be used to spend. Requires a new wallet backup.
Hint: use importmulti to import more than one public key.
Note: This call can take over an hour to complete if rescan is true, during that time, other rpc calls
may report that the imported pubkey exists but related transactions are still missing, leading to temporarily incorrect/bogus balances and unspent outputs until rescan completes.
Note: Use "getwalletinfo" to query the scanning progress.
Arguments:
1. pubkey (string, required) The hex-encoded public key
2. label (string, optional, default="") An optional label
3. rescan (boolean, optional, default=true) Rescan the wallet for transactions
Result:
null (json null)
Examples:
Import a public key with rescan
> bitcoin-cli importpubkey "mypubkey"
Import using a label without rescan
> bitcoin-cli importpubkey "mypubkey" "testing" false
I tried to setup a watch-only wallet with Electrum for the Satoshi and Patoshi "addresses", well that failed apparently because you can't subscribe with Electrum to such P2PK transactions. They seem all to be P2PK coinbase transactions with are "invisible" for Electrum. My "Patoshi" watch-only wallet sees only the spam transactions to the "derived" PKH addresses.

Maybe with Bitcoin Core, but I've not yet processed what is stated in https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md and I'm not sure if and how to use it.

Maybe, in that time, people could create both P2PK and p2pkh outputs. Right?
Correct.I got my dates wrong above. I thought P2PKH came later. The first P2PKH transaction was actually in January 2009: https://mempool.space/tx/6f7cf9580f1c2dfb3c4d5d043cdbb128c640e3f20161245aa7372e9666168516
P2PK was commonly used for some time after that, and indeed, can still be used if you wanted to.
Of note, mempool.space correctly segregates transactions based on P2PK and P2PKH.
Maybe, in that time, people could create both P2PK and p2pkh outputs. Right?
I think so, yes. 
This is an issue with blockchain explorers incorrectly linking P2PK coins to the addresses we are now more familiar with that didn't even exist at the time the P2PK outputs were created.
You are saying that there was no address when the transaction mentioned by LoyceV was made? Am I getting you correctly?If so, electrum shouldn't show any transactions made before that transaction? Right?
But if you import 19uf6F6EDijkH4ZUaqsi3pZ2SVD6A5RG8X into electrum, you will see some transactions made on February 6, 2010 (11 days before the transaction mentioned by LoyceV)
What am I missing here?

Interesting. Does seem to be an issue. The relevant replies by SomberNight make no mention of airgapped use:https://github.com/spesmilo/electrum/issues/5497#issuecomment-509690955
https://github.com/spesmilo/electrum/pull/3125#issue-268581561
Perhaps there is a way around it by crafting a transaction using the pubkey and the command line, but I'd have to tinker for a while when I'm not on mobile to figure it out.
Also note that Electrum can indeed successfully sweep coins from P2PK inputs; it just won't let you watch them as you can for an address.
I did not know this (and it is the main part of my problem). From what I was told, Fork wallets can't do this (but I don't want to expose the private key to test it).If Electrum can sweep/import private keys with P2PK-funds, it's not possible to sign offline if it can't import the balance from the pubkey. Considering all of those have a very valuable balance, that's a big shortcoming.
This is not an issue on blockchain explorer as the address is linked to its public key.
Just to be pedantic, but actually you are considering the issue in reverse. This is an issue with blockchain explorers incorrectly linking P2PK coins to the addresses we are now more familiar with that Also note that Electrum can indeed successfully sweep coins from P2PK inputs; it just won't let you watch them as you can for an address.
I can't really find much information about this, searching on keywords give completely different results.
I think the replies made in the topic created by BlackHatCoiner last year should be helpful. He asked the same question.Electrum doesn't show rewarded coins
That btt link gives detailed explanation. Which means it was public key paid to, not to address. If address was imported, only the bitcoin sent to the address which is hash of public key is shown on Electrum. This is not an issue on blockchain explorer as the address is linked to its public key.

Does Electrum simply not care about the few (but highly funded!) old addresses out there? Or am I missing something?
I've found here an explanation.
From my understanding P2PK does not translate clearly to an address so we could say it's that the one who has received the funds.
I just found out Electrum can't handle "send to pubkey" inputs. If you for instance import 1PTYXwamXXgQoAhDbmUf98rY2Pg1pYXhin (to create a new watch-only wallet), it shows all the spam transactions it received and a total balance of 0.00181009 BTC. The real balance is 3,233.17181009 BTC.
I can't really find much information about this, searching on keywords give completely different results. Is this a bug? Does Electrum simply not care about the few (but highly funded!) old addresses out there? Or am I missing something?
Until a week ago, I didn't even know "send to pubkey" exists. I clearly joined Bitcoin late.
