I think it's laughable that you differentiate between the notifications of an app vs the notifications from a web app. Both are opt-in, with web apps being even more explicit about the opt-in process, in my opinion. Also, once you disallow notifications, the web app will not be able to request permissions again. Why do you feel this is problematic?
It's easy to disable notifications for native apps (on iOS at least) - just don't grant the permission in the first place.
The reason I feel web notifications are more problematic is the nagging aspect that I think would happen (like, for example, the 'install our app' interstitials and prompts). That's annoying enough without adding notifications to the mix.
I sort of agree with you. The web is the wild west, reckless and unrestricted. The app stores are considerably more tame, yet intrinsically restrictive in many ways. Eventually we will tame the web app/PWA ecosystem, while keeping things much more flexible than the app stores. I agree some aspects of PWAs are a little rough round the edges (as you described), but there is plenty of polishing ongoing, and I bet PWAs will eventually emerge shinier than their native counterparts.
