There is no need, therefore, to replicate those same definitions in
Wikidata by creating a new Wikidata item (topic / entity) for each
external vocabulary class or subclass or property.
Instead, the best practice is to simply POINT to those external
definitions, such as those in Schema.org, DBPedia.org, MusicBrainz,
etc., etc.
Agreed. If the external definition is compatible, just link it. A
specific item needs to be created only where the two definitions are
incompatible. I would define two items to be equivalent iff swapping
them doesn't change the truthness of any statement or inference on
Wikidata
(https://en.wikipedia.org/wiki/Equivalence_relation#Well-definedness_under_an_equivalence_relation
). Makes sense?
I don't know if Q474191 and Q26869695 are incompatible definitions; I
understood you claimed they were. If the two definitions are compatible,
we can merge the two items and just consider Q474191 equivalent to
SchemaOrg's definition of "Diet".
