I was hoping that what David Wood has said above is how we would
approach the discussion around the whole '@graph'/Quads feature in JSON-LD.

That is, I think JSON-LD proposes how we do named graphs/datasets in a
certain way that makes sense to us (at Digital Bazaar) and us (in the
JSON-LD CG). I think that should put pressure on the RDF WG to figure
out the RDF Concepts around datasets and Quads. It should not put
pressure on JSON-LD to remove a feature that's not fully baked in RDF
Concepts yet.

I'm going to push back on any notion that we should remove or cripple
'@graph' because the RDF Concepts are not worked out on the feature yet.
We don't need the RDF Concepts to be worked out for '@graph' to do
something useful in JSON-LD. More specifically, Digital Bazaar doesn't
need the RDF Concepts to be worked out to put the '@graph' feature to
good use (annotating graph provenance, digital signatures on graphs,
being able to express multiple sources of information in the same
JSON-LD document, etc.)

We should continue to have the hard discussion of datasets/@graph and
Quads instead of attempting to not have that discussion due to time
constraints by putting @graph at risk.
