Having worked on a cross platform application that defined the UI via HTML I'm still kinda confused about this use case - it's super trivial to wrap a set of HTML + JS in an app that's essentially just a full screen webkit/whatever window and distribute this.
The advantage of PWAs then seems to be the ability to dodge the app store certification which, while onerous, is not a bad thing for your clients.
This is equal to saying “I’m ok with Apple having a censorship monopoly of what an iPhone can run”. I don’t think the majority of people here would agree with that. I also don’t think users buying a device that is supposed to support web apps would be happy to find out that in fact it doesn’t. I’m one of those very unhappy users.
