Nah, I think I prefer keeping the safety. :)

Are you pushing with "git push --tags", "git push --follow-tags", "git
push origin tag for-linus", or "git push origin for-linus"?  It's
possible that the last two should *always* allow overwriting tags
(regardless of whether the change is a fast-forward update), though I
haven't thought it through carefully.  In the former two cases, the
check for moving an existing tag seems useful and worth preserving.

In the meantime, a command like "git push origin +for-linus" seems
like a pleasant way to get the job done.  That way, nothing bad
happens if you get distracted and forget to add the for-linus argument
(unlike "git push -f origin").
