"It is a building block for a variety of improvements," Wuille told CoinDesk, adding there are even some further-out improvements that haven't gotten a lot of attention quite yet. And while Wuille hopes the change will ultimately be adopted, he added it's "ultimately up to the users" if they want to adopt it - as was the case with SegWit.
Shit, did they actually bother to talk to Bitcoin's developers!!!? What the fuck is going on in the cryptocurrency press, they NEVER talk to the Bitcoin devs
Schnorr sigs will be a significant change (although I'm not convinced about Coindek.com's assertion that the code will change alot, apparently the secp256k elliptic curve library, written specifically for Bitcoin, will still be used for Schnorr sigs).
Enabling signature aggregation (where 1 signature can be computed for several private keys) will make privacy schemes easier and more attractive, but more importantly will actually improve Bitcoin's scaling factor. So few people ever say anything about this: just changing the blocksize means using more resources at the exact same scale i.e. changing the blocksize does not change the scale. This improvement (where the average signature size is reduced by 25-30%) means that the current Bitcoin maximum block limit of 4MB can fit more transaction information into it, hence this is an actual scaling solution.
