I'm sure that it's possible to use push notifications in a way that benefits the user. I'm also sure that this almost never actually happens.

Notification are such a plague that I simply won't allow them, period.

Aren't there some cases where they could be valuable? like alert that plane is delayed before you leave for airport or that your uber has arrived outside?

Yes, as I acknowledged in my comment. But notifications have been so widely abused as to reduce their utility for cases where they would have been useful.

For me, the notification bridge has already been burnt to the ground, though. There is every reason to expect that allowing any application to do notifications will result in garbage ones as well as useful ones.
