The Photos app does not need permission any more than any other Photos app. It can ask "Photos app wants to access your photos" and you can click "Always", "Selected Photos", "No" and download some other app to access your photos. That would be the "equal" thing to do. Let the user pick what app they want to access their photos with.

Same with the Camera App. It can ask "Camera App wants to access your Camera" and you can say "No" and then download some other camera app and make that your default and grant it camera permission.
