I'm having trouble figuring out why the working group should do anything here, 
particularly at this late date.  Is it something that needs to be done because 
the current situation is horribly broken? Or is it something that needs to be 
done because the WG charter requires it?  I don't see that either is the case.

So maybe we can re-define the 2004 regimes as we go, as well as our newly preferred "backbone". The 2004 regimes were written to exactly match the rdf, rdfs and rdfs+datatypes namespaces, so it would not be outrageously strange to repeat these in the revized specs, if only for historical interest.
