I shipped a PWA in the Play Store. Guess what? It still got delisted because I didn't update to the latest API level or whatever.
Unfortunately you can't just ship a PWA with no wrapper. You have to build a special wrapper app that hosts the PWA and you have to use Android Studio and Gradle and all that crap.
Updating the wrapper is surely still easier than a whole app, but it's nontrivial and it's frustrating to still have to deal with the platform BS for a pure web app that uses no platform APIs at all. More work than I wanted to deal with for a hobby project, anyway.
