📝 Original message:I agree with Matt. The less said about the "Aw shucks Jeremy didn't know that CTV didn't have community consensus at the time" [0] and "it was the lack of process that was the problem" the better. If people don't care about lack of community consensus there is no process in a permissionless, open source community that can stop them or direct them down a more patient, productive path (I tried). I think it is a shame because I think (maybe I'm wrong) at least in the technical community there is an understanding that long term Bitcoin is far from finished in exhausting its potential and we do need people who will work on changes that we'll need in the long term.

There are a few interesting things in here though. I'm not convinced by the name (bitcoin-inquisition, shedpaint, shedpaint, let's park that for the moment) but I do like the idea of signet having soft fork proposals enabled on it [1] whether that be CTV, APO etc and if that requires more of the signet code to be moved out of the Core repo so be it. I'm surprised more isn't being done on Liquid already with what possible future functionality is (and could be) enabled [2] there but maybe there is more happening than I'm aware of. Protocols or use cases built out and demonstrated on signet (and/or Liquid/sidechains) seem an obvious stepping stone to me for convincing the community that it is potentially worth taking the chain split risk for a particular upgrade. It is a long slog to get community consensus on an upgrade (Taproot certainly was a slog) but I think the vast majority of us think Taproot was worth that slog and Bitcoin would be poorer today without it.

The Great Consensus Cleanup is an interesting example in that I get Matt doesn't have time to champion it or focus on it with his LDK commitments but I have no idea where it would rank on his long term priority list if he wasn't working on LDK. Similarly I have no idea what people who understand this evolving system much better than I do are thinking with regards to say adding new opcodes, sighash flags versus say waiting on Simplicity and possibly adding new functionality within that potential upgrade. For people like me who are extremely unlikely to propose their own consensus change(s) getting some signal on what to spend time digging into would be useful rather than second guessing what people are thinking. There is a danger that you flirt with perceived public roadmaps when possible authority figures stick their necks out and effectively say "I'm not in charge but in an imaginary world where I was this is my current thinking of the ordering in which we could improve this system long term. But this could change depending on x, y and z and possible upgrades are only ready when they're ready and they have community consensus." There is no way people don't play these exercises in their minds. I do, I just have very few answers :) I personally think APO is in prime position to improve Lightning channel state management with eltoo and if it enables some covenant schemes too that seems like an added bonus. On APO versus waiting for APO like functionality in Simplicity I have no idea. Work on APO/eltoo and Simplicity both seem to be progressing in parallel so the APO versus Simplicity discussion perhaps rests on whether people think certain covenants should only really be enabled once we have the security guarantees of Simplicity [3] (if at all).

Antoine's covenant R&D effort [4] seems really promising and I hope the shenanigans from earlier in the year don't put people off from engaging with that. Hopefully we can see more exploration, development and research in covenants (e.g. this excellent research paper "Bitcoin Covenants: Three Ways to Control the Future" [5]) and we can foster a community which has very high standards, is open to new ideas and new research but can avoid these months long resisting chain split fights. I think the discussion would be much more interesting and much more productive if people didn't have to think "If I express a view now it will be used to attack me personally later" or worse "If I express a view now it will be used to justify an upcoming chain split".
