Thank you for your comment. Well as you may have followed the short read, PWAs are not exactly apps, they still remain to be pure web applications with a url. It's just Chrome that makes it look like they are a real app. The apk is generated by Chrome directly. This gives power directly to the browsers. Other browsers for instance do not do that, they just create Android shortcuts. Some interesting idea that just came to me is that maybe app stores can make a special section for PWA and then it's up to them to generate the same apk just like Chrome does. But yeah, the store has to be installed on the phone, otherwise discoverability is hard. In the end, a PWA is just a manifest file + everything happening in the web application. I use twitter like that and I know many people who use facebook like that - this way at least Facebook or Twitter cannot mess with the local data of the user's device.
