Substitute the word "needlessly complex" for "overengineered" and I
don't like it either. But 1), I don't think you'd get anywhere near
universal agreement that by_path, by_id, etc is either overengineered
or needlessly complex, and 2) ANYBODY can make a typo, completely
unrelated to "not bothering to look at dmesg | tail". I think a more
relevant constructive criticism would have been "where were the
backups?".
