Even in the extreme unlikely case of opening up Apps without App Store. People will still be using apps. Even if they are Web Apps or Apps with WebView. It will still be Apps. Simply because accessing a button is easier than typing in a link.
How is a home screen app icon different from a tab in your browser, if it leads to what is essentially a web app? I count such apps as a success wrt "betting on the web".
Sadly, the capabilities of PWAs are very much second class on every mobile platform right now. But I don't think it will stay that way forever.
Web is still great for Discovery though.
