Says who? Seriously, I don't like that contract, and I can think of others I
like better. I don't see how we can decide such things by fiat. Merely
saying "this is the contract" doesn't make it so. There are different use
cases here, or so I've been trying to suggest.

Plus, according to yr rendering of "the contract", I can't do any inference
at all. None. Inference may well add triples to the dataset "described by
the requester".

I understand that.

And I expect other services will be "run this query against some graphs I
list in FROM NAMED as well as against other triples the service provides".
