I can download 95% of apps in under 30 seconds and all of my apps update whilst I am sleeping. And nothing is stopping you downloading new content in a native app which is where the majority of use cases stem from.

No one will demand it. You're just giving your users a worse experience. App store developers are people who have given up on speed. Y'all think a 30 second delay between screens with several pointless clicks is an acceptable user experience. It's sad.
