Sorry for seeing the reply so late. This is an interesting idea, and my inspiration comes from Shizuku on Android, which allows granting permission only once using adb commands, and then other apps can use advanced Android APIs through this app without each app having to handle it via command line each time. https://shizuku.rikka.app/

So I think it's possible for Web Apps to have a similar experience. Currently, the Chrome WebStore version has been approved, and Firefox/Safari are under review. Hopefully, this extension can eventually be used in all major browsers (including mobile support for plugins like Kiwi/Edge/Safari).
