It is not file cache or local storage the main obstacles for the wide adoption of PWAs, it is the restriction to easily access phone features. Even something as trivial as "take picture + upload" or "get gps data" is currently a pain.

A gazillion apps, checked and approved by app stores, are already doing whatever the f* they want with user data.
