Right, it is closely coupled - as is any other interaction driven by
shared understanding between the client and the server. Not everything
needs, or can be, visible on the network and is better off dealt with
via shared understanding between client and server. What is it about
the non-partial'ness of PUT that requires it to be made visible by
HTTP across the web as a whole?
