This kind of guidelines also kind of do not treat PWA style apps well, or could even prevent adding app that is similar to another app already existing at App Store:
https://developer.apple.com/app-store/review/guidelines/
> 4.2 Minimum Functionality
> Your app should include features, content, and UI that elevate it beyond a repackaged website. If your app is not particularly useful, unique, or “app-like,” it doesn’t belong on the App Store. If your App doesn’t provide some sort of lasting entertainment value or adequate utility, it may not be accepted. Apps that are simply a song or movie should be submitted to the iTunes Store. Apps that are simply a book or game guide should be submitted to the Apple Books Store.
Are there any widespread apps that are more efficient than these? I really would like to know.
The webapps you have used are slow.
This generalization is changing and will continue to change the better Apple/iOS treat PWAs.
