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
Finally, I'm not in favor of deprecating UNIFIED. I just picked that as
