Just looking through the apps I currently have open… Bank app, chat app, maps, Tile, YouTube and a weather app. Only one of them is actually doing anything that wouldn’t fit a PWA. So why are they apps, not a collection of links?
I would say only the weather and bank apps would be really equal as a PWA.
Maps require complex gestures and advanced graphics and UIs that would never work well as a PWA. Try maps.google.com. Its nothing like the Google Maps app. Plus Android Auto integration.
Tile probably needs pretty deep Bluetooth integration and background processing that the web doesn't provide.
YouTube can do things like PiP that you can't do on the web.
