It seems to me that Wikidata's roll-out plans have been poorly discussed on English Wikipedia. Signpost is a reporting mechanism and clearly does not represent a consensus for deployment. I see from the latest signpost linked to above that there is "an RFC out there". I am trying to locate that RFC. In the meantime, I do understand the power of what you are trying to achieve; I just think Wikidata has not thought through deployment communications properly  (talk)
