I make draft PRs early, so that others know what I am working on, and can help/comment, but I know the kind of people I sometimes work with so… some commit messages I used in this month:
• DROP DROP DROP DROP
• DO NOT MERGE DO NOT MERGE
and my favorite: THIS IS UTTERLY BROKEN-LOOK-NO MERGE

@fasterthanli.me in this post of yours (fasterthanli.me/articles/jus...) the link to Wikipedia about the possible acquisition is now a broken link, because the fragment has changed. (by the way the feedback button disappeared, you might want to bring that back)
