I would very strongly recommend to use Semantic MediaWiki for this use case. It is more powerful, we use SMW in other WMF contexts already, and supporting the data inside Meta (instead of inside Wikidata and then transcluding it) allows us also to generate workflows in Meta involving local User-accounts, etc., and reduces complexity since the data is saved in one place, and you don't have to switch between Meta and Wikidata to update the data for an extension. It also frees Wikidata for having have to extend their policies to support this specific use case (would MediaWiki extension developers all get their own item per Notability, etc.). Also, SMW already right now supports the uses cases you are asking for right now. I understand that SMW was already suggested in Bugzilla. I understand Wikidata looks more sexy right now, but I think it is not the most appropriate tool for this use case. Just my 2 cents.
