There is a huge drama lurking. Kent was very uncivilized, but did not behave worse than Linus, who is saying such things ("get your head examined") every other day. So when they now block Kent, there will be no bcachefs fixes, and there will be a huge leadership discussion, worse than before. Which could destroy the project as a whole as we know it. Many other projects died the very same way. A CoC is a huge risk.
