Presumably "similar Apps or functions" would mean that third-party Apps could once again[0] deactivate the cellular radio, to prevent tracking by the mobile network at certain times (or locations/speeds).
Not so. Those functions are OS-exclusive. It's doubtful that legislators intend the Settings app to be one of those similar apps that third parties can duplicate, and Apple would easily win any case that argued otherwise.
Perhaps I overstepped my IANAL boundaries there. But I think it shouldn’t be too difficult for Apple’s lawyers to argue that functionality built into the OS to protect location data or control the cellular radio are distinct from say, Apple’s first party Podcasts or Music apps.
