This effort needs another name.

Conflating RDF* with RDF, and repeating the same mistake with SPARQL
isn't beneficial. It simply adds too much confusion for too little
benefit (if any) .

Mapping so-called Labeled Property Graphs to RDF via syntax sugar for
RDF statement Reification is a strange target, IMHO.

Syntax Sugar != Semantics .

Syntax Sugar is about translation guidance. It is implemented by coding
a heuristic informed by syntax rather than semantics.
