This *should* is not warranted. As there is often no way to include
structured information *about* a resource in-band of the
representation (sense http/awww), or to include it in a way that is
predictable by the requester, is a perfectly reasonable choice to use
303 to interpose and therefore provide a way of supplying this "about"
information. In those cases where someone is confident enough that a
200 response would have been appropriate, that one can supply
information *about* the resource (in RDF, for instance) means that
there is an opportunity to indicate (with the potential for being much
more precise than http) where that "representation" can be fetched
