For the record, the message I gave that title to was (if memory serves)
really about the fact that I wanted there to be a response header that
identified the resource, so that caches would have a unique cache key
for a resource.  I got what I wanted: Location can now be used for
2xx responses.  What I didn't get (unless this has changed since last
reading) was language in the spec describing the impact on caches of
this header for 2xx responses.
