Thanks Federico.  Much appreciated, but...besides creating extra layers inside of Wikidata just to expose external data correctly....

Still, there is a need to have 'external subclass' directly on the parent class of diet https://www.wikidata.org/wiki/Q474191

One reason is to ease the burden of SPARQL queries for both sides.  Wikidata users/developers and Schema.org

We are tracking all of the work here: https://github.com/schemaorg/schemaorg/issues/280

SELECT * WHERE {
{?property wdt:P2235 ?extsuper.}
UNION { ?property wdt:P2236 ?extsub. }
UNION { ?property wdt:P1628 ?extequiv. }
UNION { ?property wdt:P1709 ?_equivalent_class. }
FILTER( REGEX(STR(?extequiv), "schema.org") ||
  REGEX(STR(?extsub), "schema.org") ||
  REGEX(STR(?extsuper), "schema.org") ||
  REGEX(STR(?_equivalent_class), "schema.org")
)
}
