We make Facebook apps for YouTube channels, and the removal of app notifications definitely hasn't hurt us. In fact, it may have even helped, as we are no longer getting lost in a pile of app spam. Our users actually want to be notified when new videos are available! Over 50% of them sign up for e-mail notifications, and slightly less than that get the notifications directly in their Feed. We don't trick them into doing this, and it is easy to opt out. As long as you provide a service people actually want, I think you'll be safe regardless of what changes Facebook makes to its policies.
