I would suggest that a requirement for a foo:wikidata=* tag (or
wikidata:foo=* tag) is that foo=* is already an established tag. After all,
the point of linking to Wikidata in the first place is we want a semantic
way of indicating an entity.
For example, there are lots of things named McDonald's and this makes
something like name=McDonald's or brand=McDonald's ambiguous. But by
linking to a particular McDonald's in Wikidata, we specify exactly which
McDonald's we are talking about.
Thus, I think that brand:wikidata=* or operator:wikidata=* is a semantic
version of brand=* and operator=*. So, foo:wikidata=* makes a lot of sense
if we already have foo=* in the first place.
