What am I missing?    JSON-LD is an RDF syntax, so it makes no sense to 
use it as a SPARQL Result Format.  SPARQL result formats are rows, not 
graphs.

Of course, JSON-LD is perfectly reasonable, and fully supported by 
current specs, as the output of a SPARQL CONSTRUCT query.   So if you 
want to query from JSON-LD to JSON-LD, then just do a SPARQL CONSTRUCT 
query, with the right Accept: header, right?    (assuming the server 
supports JSON-LD, which I expect they all will shortly.)
