We don't do stringprep for roster groups.  Perhaps we should, but  
that's a different topic.

The reason I have an issue is because there exists logic, database  
structure, test cases, and the like to deal with JIDs as octets, all  
of which code can be reused if we pick the same approach.  If we pick  
a different one, even if we think it's better, it will lead to  
increased cost, complexity, and brittleness in server implementations.
