Well, not quite.  If you see the first email in this chain, I mentioned 
that there was a misunderstanding in the WG.  Some people thought that 
UNIFIED meant what the current standard states, and some people thought 
that it meant what I'm suggesting for KIND_OF_UNIFIED.  So, in some 
sense, we voted on something not all of us wanted.

Also, just so someone doesn't use my statement out-of-context, I said 
that we can deprecate UNIFIED, assuming that there is another model like 
KIND_OF_UNIFIED.

Finally, I'm not in favor of deprecating UNIFIED.  I just picked that as 
the preferred option compared to changing its semantics.
