We generally discourage foreign keys (that are only usable together with a different data set and that are not signposted locally). When Wikidata keys were first added to OSM, I thought this was something limited to place names of a certain importance and I didn't object. Seeing that this now leads to the automatic assumption that Wikidata IDs are practically admissible *everywhere* where Wikidata has defined an ID, I am having second thoughts about the whole issue. In theory, almost everything we map could be expressed by a Wikidata ID. If welcoming a Wikidata link on a city place node means that by extension I also have to welcome "amenity:wikidata=Q123456" on something that is, say, an ice cream parlour because Q123456 is the generic Wikidata category for ice cream parlours, then I think I'd rather not have any Wikidata links in OSM at all.
