RightsManager plugin (included in the core) should take care of
cleaning groups when user is removed, if it does not : you xwiki is
older than 1.2, rightsmanager plugin is not enabled in the xwiki.cfg
(it is by default) or there is a bug.

Anyway i totally agree with you, for me XWikiAllGroup should be a
"virtual" group. It was just a comment ;)
