Yeah, I get that a lot. I don't believe in commit messages. I know that 99% of developers are disturbed by this, but I think it's the best way to work so I'm willing to deal with people not liking it.
Also, commit messages are a form of documentation; but they are one of the least useful ones. Much less useful in my opinion than docstrings, topical guides, references and blog posts. So I think that spending time on them is a much lower priority than spending time on the other kinds of documentation.
