Just checked and Android has this permission too: I can select "Allow limited access", but this requires manual configuring where you select specific photos/videos/albums to be accessible. It's so bizarre.
You're not providing a one-time access to the photo in this case, you're providing perpetual access to the uri.
If it loses access, it won't be able to display the media from your local storage. And of course, you wouldn't want it to duplicate the media because that'll take up extra storage.
