@MisterSynergy started running a bot task on Wikidata today that protects high visibility items on Wikidata. The changes in protection levels appear on English Wikipedia watchlists (and presumably also in other languages) e.g., as:
"(diff | hist) . . Dm Template:Cite Q/testcases (Q6654); 18:04 . . MsynABot (talk | contribs) (Protected "Q6654": Highly used item: to be indefinitely semi-protected per Wikidata:Page protection policy#Highly used items; please use Template:Edit request on the item talk page if you cannot edit this item ([Edit=Allow only autoconfirmed users] (indefinite)))"

EDIT: Some of the log items in concern on the Wikidata side:
