On the one hand I love this. I'm glad PWAs are helping drive people who wants and expect a certain thing towards the web.
I am also however super sad that PWAs removed so much greatness of the web. Most don't launch in the browser. None have visible url bars. They just added a new mode so PWAs can have some kind of tabs. They don't integrate with bookmarks, or extensions. They don't have forward/back. I like the web a lot, and I feel like PWAs are a major step backwards for me.
What's really scary to me js that new permissions are being added which are PWA only. I no longer can have a web like experience; I am forced to have an app like experience, without any of the affordances I get with a user agent/browser at my back. I feel so undermined here.
