I sent a long email to Wikimedia-l and also made the same post to Meta. I published a new paper recently with a proposal for a multilingual Wikipedia and more, and, unsurprisingly, Wikidata plays a central role in that proposal. I am trying to have the discussion not to be too fragmented, so I hope it will happen on Meta or on Wikimedia-l, but I also wanted to give a ping here.
Stay safe! Denny
