Recent Flow deployment on French Wikipedia raised some feedback (here, here, here) about noisy notifications, sent to all users when a new topic is created on a page they watch. That problem is not new at all: T100528#1468476
I'm creating that task as a sub-tack of T100528: Improve organization and control for Flow notifications (tracking + ideas) in order to track if it is possible to find a way to (temporary but urgently) fix that problem.
