I understand the intention behind the RFC but it's pretty clear that if enforced these changes would effectively ruin Wikidata. This underlying issue is that Wikidata does not have a good enough mechanism to fully cite the way Wikipedia does, and even Wikipedia does not require the type of granularity that would be needed to support every statement -- it would be impossible. In Wikipedia you can cite paragraphs and be relatively safe.
I think this is why it is even more critical that it is possible to add really robust, clean citations (not just URLs) to Wikidata. It needs to be better because the validity of BLP concerns is not a trivial thing.
This whole issue is why I am obsessed with adding citations on Wikipedia. If I add information I always try to cite it -- otherwise it has typically been deleted. This often makes editing difficult, but how can this requirement be made of the encyclopedias, Wikimedia Commons, etc. and not of Wikidata? I understand a blanked CC0 or whathaveyou of a data set. But for a lot of content -- but biographical entries especially? That's a problem.
Not trying to be a pain and I want to support the consensus on this RFC but hesitate to do so without further discussion of solutions.
