I agree.  I was trying to suggest that these questions are what the 
front end needs to care about, not about versioning specifically.  If 
these questions are turned into target hooks, all of the logic specific 
to versioning can be contained in the target.

My only question intended to be answered by humans is, do people think 
moving the versioning logic behind more generic target hooks is worthwhile?
