I've actually been thinking to restructure the TXHASH BIP as an upgrade of CTV. I believe CTV is mature enough to start activation signaling tomorrow. And I'm in favor of doing that. I don't want TXHASH work to hold it back. It can perfectly be structured as a CTV upgrade without much technical debt.

On the other hand this is sad because Mercury statechains require APO (or I believe some of the TXHASH flags that emulate APO -- or CSFS or LNHANCE) in order to work and that is one of the things I have most hope for in the current days of Bitcoin. But whatever, I'm happy if we can make any soft-fork if that is going to encourage further ones and CTV should probably be the first since it's so appallingly simple.
sir, i cannot zap you for this eminently zap-worthy comment
