Agreed.

Well, I think there is strong support for updating either all graphs, or a 
named graph, but have anyone come forward with a case for updating more than 
one named graph in a single query?

I think INSERT INTO <uri> is very important, but I don't know if there needs 
to be support for multiple graphs.

Good. Also, HTTP protocol use, I don't to what extent we should view that as 
separate?
