Maybe that will work in practice but you have no way of knowing if it does. There is nothing really preventing Apple from sneaking tracking data through the notification channel (not to mention that centralized notifications are already a juicy opportunity to profile and track users) or retaining the data and sending it off when you do OS updates. Once a company has shown willingness to go against your interest you can't really trust them. The only real solution is to use software that respects you and increasingly that means only open source software.
