I think this work is great and interesting, and I respect it. One of the things I feel like it lacks is a discussion of the broader context: we all sort of suspect that one of the reasons Twitter does not generally allow for de-escalation (like FB not censoring misleading news articles) is that such escalation is in fact part of their revenue stream (escalation=more engagement), so while I think ideas like this would be great if Twitter decided to incorporate it, the issue of course is that Twitter wouldn't want to as they actually love the cancel culture mill, it generates engagement.
I genuinely however like the ability to admit guilt such that replies are disabled because as the author notes, it explicitly ends all engagement. Any following engagement would require more work (subtweeting, screenshotting) but actively put a damp on the first derivative. But that said, reducing engagement is in fact not in Twitter's interest, as I said, so I don't see them doing it without some outside pressure.
