By mixing WikiTree people and WikiTree categories in one Wikidata property will makes this less useful as Categories for e.g. a Swedish Parish in WikiTree could be same as two objects in Wikidata as we have decided to model the objects in a different way in Wikidata. This can be handled with exceptions (see Property 778) but splitting the property in one for human and one for Categories/Spaces feels a cleaner solution
