If we do it during pull, would we just warn? how would we reject commits? that doesn't really fit.. We can't do it during commit, as obviously the broken machine will likely not be able to notice it at all.. We could check remotes during push but that doesn't solve this either.. Maybe just emitting a warning during a fetch or am (since am doesn't use pull) would make the most sense? I don't think we can reject things when doing a fetch though, but we could warn.
