I think it's useful to be able to query all streets named after a certain poet or celebrity. I did the exercise for Father Damien and Guido Gezelle and it's not possible to simply query for "Gezelle" and obtain the same result.
You are right in that this is a query on name:etymology:wikidata and. It's also interesting to be able to find all the artwork by a certain artist. I've been doing this for Ad Wouters. There are however several persons by that rather common name. They're not all artists, but simply querying on the artist's name is not sufficient. Anyway, my conclusion is that wikidata and *:wikidata tags are useful and the only way that makes sense to use them, is by adding them to the OSM objects themselves. Then when a node gets converted to a (closed) way or a way needs to be represented as a relation (multipolygon, maybe) the wikidata tag(s) simply follow(s).
