Its about the app being too slow to use on browser mode. If it's too slow then people won't use it no matter how nice your app looks and most browser websites are just too slow compared to apps. Yes, Google is adding restrictions but the majority of people don't care about that, only a tiny amount of people care about that, so you will end up with a dead app because lack of users. There is some PWAs, which sometimes you can get the user to install it, but it still not as fast a native. If you have a dev you could make it so the users won't notice the speed difference but apps still win.
