Noted. Sadly I just don't have much appetite for that sort of thing atm. I'd love to hear someone I stole my opinions from argue against some of these points though. There's some confusion and doubts I've always had about SPV nodes and that sort of thing, even though I've read several long form posts about the whole thing in the past. And the RBF/zero-conf stuff is murky to me as well. Let you know if I end up picking it up though
