I'd rather something tell me exactly why this popped up in the first place, as every new OS version seems to introduce more triggers. I have apps that now pop this up when I quit, which doesn't make much sense.

Ideally, every API to call a function that provides the developer "dangerous" access to your system, should give the developer a text string argument to explain/justify to the user why it's needed. Then, instead of a confusing "Do you want this app to use Bluetooth?" pop-up with zero context, you let the developer convince the user.

Agree with that, I like the idea of permissions for specific things like this but it’s way to hard to know what’s actually being asked and why.
