Ummm... that just seems totally confused to me.  We won't provide a way
to negotiate feature X because no one currently uses feature X - but if you
can't negotiate it, what use is it to implement it?  (Other than in a 
private, non-RFC-based, non-interoperable setup.)

It just asks people to either ignore the standard and go totally
proprietary, extend it ad-hoc and quite possibly incompatibly, or
cut off any work on using those annexes ever.

Which is basically a private, incompatible negotiation.


I realize this is the way the RFC is; I'm just wondering as to why.  Maybe
the point was no one had implemented them and the WG believed no would
would implement them for good reason, and they were effectively deprecated.
