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.
