I don't know why this is downvoted. There are definitely a ton of users who will accidentally delete the camera and then complain their phone is broken, wasting everyone's time.
People have already apps they can delete. And when they do it by mistake, they just go to the App Store to download it again, wasting nobody’s time. Why would it be any different?
There’s just need to be a button in the settings if the App Store itself is deleted.
