Sorry it took me long to answer, but I wanted to run my answer by the WG
so I could speak on its behalf. Although we know application/json could
suffice, we felt that it'd be important to distinguish between JSON
encoded graphs and SPARQL results format. Admittedly, JSON is a data
model, but unfortunately, there are no conventions to specify the model
type. This the same reason why we didn't use application/xml for SPARQL
Results XML Format to be able to distinguish it from RDF/XML.
