One of the issues I frequently observed is that mappers keep trying to add a wikidata=... tag even when there is no perfect match. Having a part:wikidata or a similar tag would help those mappers - indicating that there is no perfect 1:1 match, but someone already looked at this specific object and found another item to be a partial match.
