In what sense is it a corner case? Indeed, for SPARQL/Update, the URI is just 
a name and not different from any other name, but for the HTTP server it is 
what makes it simple and straightforward from a Webarch and REST perspective.

This is, if I understand you correctly, almost the opposite of my proposal. I 
think that a) should be the requirement, b1) ignored, and b2) mostly left to 
the language, but a time-permitting feature if we can find a way to 
gracefully reconcile it with Webarch and REST.
