A lot of comments seem to be missing that the issue is less about permission granularity and more about pre-asking for any and all permissions that the app may use. Runtime permissions would solve the issue - using the camera? Ask the user. Then the user can decide to allow once or allow every time. Of course, you'd have exceptions for some common things - store data etc.

The current model is rather like giving a teenager a credit card and hoping they'll be responsible rather than giving them an allowance or having them ask you when they need money. The user has no clue how the permissions are being used after they're forced to allow during installation.
