It's an easy migration path that allows publishers to sprinkle in a bit of RDF into their existing JSON APIs *if* they want. And consumers can use a bit of RDF *if* they want. And hopefully it might get more and more over time.

It's well possible that a solution for #1 would also address #3. A solution designed purely to satisfy #3 would obviously not satisfy #1 because it can't be consumed as RDF.
