It's not unheard of - iOS already provides granular permission capabilities for photos. You don't have to give all-or-nothing permission to apps to access photos anymore; you can now choose precisely which photos the app has access to. I'm looking forward to iOS doing the same for contacts; there's no reason why WhatsApp/Telegram/etc need access to my entire address book if I just want to call Steve.
