I disagree pretty strongly; caches can occur within the origin server (and one of the implementers interested in cache is doing exactly that), and caching semantics are detailed enough that they deserve separate attention and communication. 

Besides, we're trying to pave cowpaths here; Cache follows X-Cache, and this header is trying to align a variety of other behaviours. Let's not get too ambitious.
