A web browser in 2020 is a place to run vast swathes of untrusted code safely; it is not a digital workstation platform, that is the job of the OS. I'm not sure how much that assumption really holds any more, nor why it should necessarily continue to do so even if it has so far. Technology evolves, and so does how we use it. In the case of the web, and web apps in particular, they have evolved to satisfy a need for convenience in software distribution that many traditional desktop OSes had hopelessly neglected for a very long time and where the developer experience for native mobile apps is less than ideal. I appreciate your comment about the trust issue, but the bottom line is that these technologies do serve a useful purpose for some people -- I have the customer feedback at my own businesses to make that clear -- and the experience web developers can offer on Android with PWAs will now be significantly better than what they can offer on iOS.
