Hell no. Wikidata is first and foremost a product that is actually used. It has that way from the start. Prioritising RDF over actual practical use cases is imho wrong. If anything the continuous tinkering on the format of dumps has mostly brought us grieve. Dumps that can no longer be read like currently for the Wikidata statistics really hurt.

So lets not spend time at this time on RDF, Lets ensure that what we have works, works well and plan carefully for a better RDF but lets only have it go in production AFTER we know that it works well.
