Does that mean when I send in a test request, it's better to omit
syzkaller-bugs from the CC: list?

Also, whatever did happen to the most recent test request (the one sent
to syzbot+7fa38a608b1075dfd634 even though it was meant to test the
bug reported by syzbot+c7b0ec009a216143df30)? Did it truly fail to
build? I can't find anything about it in the dashboard link for either
bug report, and I haven't gotten a reply from syzbot.
