I just declared a moratorium against AI-written change descriptions (e.g. PR and commit messages, also issues/tickets) from my team.

AI was writing change descriptions that were worse than useless to me as I tried to review PRs: outlining details of the code that could easily be seen by looking at the code, but omitting the higher-level framing needed to understand broadly what the code is doing.
