That is too much I think? It would be weird to trust one notification provider for some stuff, and another one for others? Every user should be able to choose a "Notification Provider" is IMO enough.

On that front, there is already a push standard which is called WebPush which allows to do this seemlessly. Except it's only in browsers (also I don't think any major browser allows customizing it?). On non-Google Android, you have UnifiedPush. (It isn't a standard. Not sure it would make sense to make a standard of an Android API?)

I've been thinking of making a OwnerOS: a bare Android who lets users pick every component they want. You select which store you want, which assistant you want, which notification provider you want, which SystemUI you want etc. All of which currently require to root your device to customize.

My understanding is that this uses centralized servers maintained by each browser vendor.
