Ultimately I ended up making a PWA that does nothing except act as a bookmark. Which was way more of a PITA than it should have been.
Which is exactly what I was going to reply to your original post.
I am willing to bet 80-90% of user don't want / need / care if it is an Native app. They simply want the website / PWA bookmark icon on their App Screen selection.
The problem right now is the experienced of getting a PWA on to an App screen is not user friendly or in someway user hostile because it goes against the fundamental service revenue of their App Store model.
"Aim camera at QR code to put "open-link" icon on your home screen"
Does something like that not exist?
