enhancements to SPARQL property paths

Over the last few years there have been a number of research papers describing the proposed enhancement of SPARQL, in part to permit RDFS reasoning at run-time.  E.g.

  *   nSPARQL: A Navigational Languagefor RDF, Perez et al. 2010
  *   Querying Knowledge Graphs with Extended Property Paths, Fionda et al. 2018

I would be interested to know if anyone has views about these proposals, e.g. their value and workability.
