There are definitely pros and cons to part serialization. However, I think we can all agree that when Apple is selling genuine replacement parts, those parts should be ready to pair with the first phone they're put into, instantly, without needing to call Apple Support to finish the repair process. You should also be able to order the parts without needing to give Apple your device's serial number ahead of time. Otherwise, repair shops can't keep genuine parts in stock, and your ability to complete a repair is entirely dependent on whether Apple is staffing their call center sufficiently, which is currently a requirement. Optionally, maybe there would be a way where the phone could prompt the user to choose whether they want to serialize those replacement parts to this specific device, and then they would be registered with Apple, unable to be moved to a new device if this one were stolen and parted out. An automatic check for whether these parts have previously been registered would not be as onerous as a phone call.
