Its just now possible to turn it off for all apps with one swipe and on click. Like I know WhatsApp need Microphone access for voicemail, but I can turn off the access for all apps with one click and turn it one for all apps with access when I need it
No, its been there for about the same time ios. A few years ago now they changed it so that the permissions are asked for from inside the app (when X is used) instead of when installing if that is what you are thinking about
