My understanding was that to a proxy, a cookie was simply to be viewed as an 
opaque state mechanism between the client and server.

In general, the comments in the cookie drafts have been  that 
proxies shouldnt be mucking with the actual content of a 
cookie header.

I fear that your proposal would add too much complexity.  Having
some fields in a cookie which reflect users' state, ie address, 
and others which are trying to overload feature-negotiation,
seems to spell trouble.  

If the cookie is to remain a client-server only state, then
feature negotiation shouldnt be a part of it.
(since a proxy must participat in feature-negotiation )
