I have created it and no matter how you call it.
You see, he's asking if it's enough to re-establish the MultiSig wallet, if he followed the advice that the descriptor is enough.
He may count on it in case the seed phrases are gone.
As you can see, that exported descriptor wallet doesn't contain anything that can sign a transaction from either cosigner.
You can check it yourself that it contains "extended public keys" and no master private keys or seed.
Just new test.
Created 2-of-2 multisig from two BIP 39 software wallets using Sparrow as coordinator. Back-up its descriptor. Sent to its address testnet BTC . Deleted that multsig wallet and restored it from back-up descriptor. Transaction is there. From restored multisig tried to send testnet BTC back .Not possible!
Thus, if at least one of cosigner is HW then restoration from descriptor works otherwise does not.
