Cheers for the write-up, I read it end to end, but haven't managed to digest it fully.
As a community, we want to prevent the possibility of double spending the mempool with mempoolfullrbf=1. Does that means wallets should disable the option for opting out of RBF?
The way we prevent wallets from double spending is the adoption of lightning. The mempool simply can't prevent double spending reliably, and trying to do so is harmful for a lot of reasons.
We have to accept that unconfirmed is unconfirmed. Which is exactly what the supermajority of wallets do already.
