While I don't agree that it would be "useless and worse than not adding it", I appreciate your constructive criticism. I guess most of the criticism will linger on as long as Wikidata is not grown up. Which, I believe, is bad, also because the same criticism was addressed to OSM in the past (it still is, sometimes). Of course, a deeper understanding of how Wikidata deals with the scenarios you describe will be needed. Ciao, Simone
