I think you've misunderstood what PWAs are? PWAs are fundementally websites which are built on a bunch of guidelines with performance and accessibility prioritized.
And if you follow those guidelines and with the right meta data, they get treated specially by certain 3rd party, like google/android letting you update them in the app store.
Just like AMP are fundamentally websites built on a bunch of guidelines with performance and accessibility prioritized which, once you sprinkle them with enough metadata, get treated specialty by third party like google.
Yeah, I don't think I misunderstood. AMP's guidelines are just more strict before the 3rd parties start treating you specially. And in both cases, the original website/app is just fine, until it starts getting treated specially.
sorry, terrible choice of words on my part (more like the world's worse freudian slip, as I was thinking "like apps in the app store). I meant that they're going to show up like any other app in the app list, settings to be tweaked/modified/deleted and so on.
