Yes. joe and Yuri are playing around with the cache ID key produced from
combining Vary with request headers contents (the variant version of
Store-ID). Not the request message itself.

Which is part of why this is not being accepted. The server is still
delivered the same request headers. So a server that responds with SDCH
encoding to those requests with "sdch", will also be delivered to the
top for clients that dont support SDCH.
