[Bitcoin-ml] Can we decide on a roadmap now?

>Faster transaction validation

True, but that's what I mean by cosmetic. I don't think anyone would actually be able to notice this.

>Smaller transactions

Not really, the real difference is just one bit, which could be removed at a negligible performance cost.

>CoinJoin support

Everything that's possible with Schnorr is possible with ECDSA. Introducing ECDSA signature aggregation would require much smaller changes, as everything already has all needed code. Schnorr requires a much bigger update.
