Require UAs and intermediary caches to assume Vary: User-Agent

See http://www.w3.org/mid/507D94AB.3000207@mit.edu

It would be useful if the spec required that UAs and intermediary caches  
act as if all responses had Vary: User-Agent specified, since many pages  
on the Web serve different content depending on the User-Agent header but  
do not bother specifying Vary: User-Agent.

I would like this to be filed as a new issue in the issue tracker.
