Web notifications aren’t power efficient the way APNS notifications are.

That’s why it’s easy to build support for it on Desktop safari but not iOS.

I except they’ll support Web notifications on iOS once the technology is mature enough to meet the power budget.

web notifications work exactly the same way APNS do. If OS vendors are reasonable and expose the APIs needed to use them efficently that is.

This is not correct. Web push notifications rely on running a persistent service worker in a JavaScript runtime, which is not anything at all like how they are received by native iOS Apps.

Additionally with iOS apps, Apple can and does work directly with developers whose apps are overusing the notification system and draining power, which they cannot do with arbitrary web apps.
