The hate against the notification bell is unwarranted.   I never hit the bell because I don't want to be spammed with notifications.  People have dozens, to over a hundred channels they subscribe to.   I never view videos because of notifications,  I watch what I want to watch by clicking my subscription feed to view all subscribed videos.   A few channels might warrant special treatment where you really don't want to miss a video,  and so you can enable notifications rather than relying on seeing it in your subscriptions.   I don't even know why anyone would rely on notifications for videos.
