Just received confirmation via email from my adwords support rep that the QS drop is, in fact, a bug they are working now to resolve.
Yeah, but remember that AdWords reps are quite clueless when about QS and policy team. All about QS is "no, no" zone for them.
But I honestly hope it's a bug, I see my keywords having reduced QS all across the board.
