Yes, that would be a possible evolution of permissions. If an app lets you choose a picture from your photo library, iOS swaps you to your camera roll where you select the image and then click &quot;Share this image with app&quot;. You then get redirected back to the app and iOS sends the app only that image.<p>Currently, for things like camera, microphone, location, etc. you can always revoke that permission after granting it via Settings.
