We have hooks to prevent a number of things, but not the removal of
branches (or tags). We'll send an email to committers telling you it's
been done, but we don't prevent it.

It would probably be pretty easy to add a hook preventing it though -
do we want that? (we could still delete branches of course - but it
would require an admin to do it directly on the git server, which is
highly unlikely to happen by mistake)
