Thanks so much for digging this out! Very useful to know. So, the notability methodology fails massively, as many have noted. Jesus and Muhammad trailing Britney Spears by a factor of 4 or so is my favorite so far ... LOL. But the question becomes, how can the notability be improved. Of course "AI" is probably the answer here, in the same way it is becoming the answer to so many questions/problems. (Just as the answer to every legal question is "it depends".) Two elements pop to mind: (i) Accessing more things outside of the Wikipedia/Wikidata database. (ii) Within the Wiki world, making associations like Jesus ~ Christian ~ bible ~ best selling books.
