Agree this would be more correct.  The current implementation is more
optimized from performance point of view, to avoid finding all possible
values if just feature metadata is requested.  And (imho) should be more or
less consistent with the "open world concept " of RDF , that a particular
representation  doesn't necessary contain all possible triples.

Anyway, I am aware of the inconvenience, and working on allowing adding
almost arbitrary metadata to the features, but this is not yet deployed.

Indeed.
