A. But maybe Git will no longer know what you are doing.  Its standard
way of resolving references will mean that once a branch
refs/heads/wibble exists, referring to a branch wibble will become extra
hard.  For example, stuff like

push origin HEAD:refs/heads/wibble

will maybe create or update a new branch wibble, or maybe it will just
push to the existing branch refs/heads/wibble.
