I'm wondering if this behavior shouldn't belong to the extension base  
class. Just yesterday I was wishing for a way to make an extension  
non-reloadable (see http://tinyurl.com/4cwo6e). Based on the state of  
the DB or a user-set attribute, individual extensions could choose  
not to activate/reactivate.
