It's a lot easier to get the commit ID by running "pacman -Qi
<pkgname>". I'd rather do that than have to potentially redownload the
Git sources and search the commit log.

That's certainly true; however, it is useful to know which commits
still have a problem. So sending a non-HEAD commit ID is still
somewhat helpful even if upstream asks the bug reporter to test again
using HEAD.
