The problem in here is more or less awareness of sharing or how to prevent accidental sharing of face data. I can see sharing to some photo editing app in anonymized fashion being useful for certain things and better than say, using a flat photo from Instagram or Facebook, but sharing faces on social media is a lot more intentional than a small and hidden agree to share with app button.
I think a better solution is when app is specifically requesting face data, there is a 2-3 seconds mandatory decision time with the default option to be off and prompt this decision in a different UI from the classic permission request dialogue. In this way the user knows the request is different And is given time to actually decide before accidentally tapping agree.
