The point is that Apple only managed to reign in push notifications because they were able to warn/ban apps.
They can't do this with PWA.
They absolutely can.
You’re acting like there’s zero way for them to throttle what’s going on in Safari.
How do you think Google warns you when you’re going to some malware website? They keep a list somewhere. Apple could do that very easily.
Computers are very good at keeping lists.
They said "In short, my UX on iOS is better without them (web notifications) even being possible".
How could they know when Apple never implemented it?
The fact that apps had unregulated push notifications and now they don't pretty much settles the debate in my favor. Apple can regulate push notifications for PWAs in all sorts of ways outside of barring them altogether, just like they did for native apps.
