Google simply needs to add "I'm an adult" functionality to their phones. I know the author of this app and trust them, I know the functionality I want and I accept the risk because I'm a grown adult and can make my own choices.

The next API Nextcloud is asked to use it literally that - it asks you, as the user, what files you want Nextcloud to read.

But why? Just for the odd app that can't be bothered to use the new API?

Even if you trust the app, if there is a vulnerability in there, the Android sandbox provides an additional line of defense. Most apps don't have defenses of their own, the only apps that self-sandbox are web browsers.
