Idk if its not in their best interest or something, but app stores should just allow installing an "app", which is really just a bookmark to website and hides all of the normal browser UI without having to bundle the entire browser with the app.
Also I don't think web views in most app stores (namely mobile stores) ship an entire browser. As a matter of fact you're literally not allowed to ship browsers in iOS and that's a huge slice of the market on its own.
