I sort of agree with you. The web is the wild west, reckless and unrestricted. The app stores are considerably more tame, yet intrinsically restrictive in many ways. Eventually we will tame the web app/PWA ecosystem, while keeping things much more flexible than the app stores. I agree some aspects of PWAs are a little rough round the edges (as you described), but there is plenty of polishing ongoing, and I bet PWAs will eventually emerge shinier than their native counterparts.
