Provenance and debugging. It would be quite possible to record the fact that this set of triples, G, were obtained by dereferencing this uri N, at a certain time, from a certain place, with a request that looked like this and a response that had these headers and response code. The class of information that is kept for [0]. If N appeared in G, that could lead directly to inferences involving the provenance information. If later reasoning is concerned at all with the trustworthiness or up-to-dateness of the data it could look at this as well.

Keeping this quantity of information around might quickly turn out to be too data-intensive to be practical, but that's more of an engineering question. I think it does make some sense to do this in principle at least.

All the above would remain in my proposal. If you were in fact inferring triples from the 303 then those would already be in the data you are dereferencing.
