I recetly created this Wikidata:Requests for comment/A meta item namespace (Mxxx) for structured data about Wikidata. And some reply there made me aware of this proposal. I think it would basically do what I'm looking for but I wonder if it should be limited to just users or if other metadata would also be appropriate such as data about WikiProjects which currently go into the main Wikidata namespace (Q####)?
