The complaint is that it's tied to the screen, not the mainboard.

Pairing sensor and mainboard is fine as long as I can reset it when I reset the phone.

That makes sense but why is this shit glued to the screen? Every other phone has the camera, proximity sensor and whatever installed in the main body or at least makes it trivial to take off from the old screen and replace in a new one.

Also... why is there any need for the FaceID sensor to be paired? It's two LEDs illuminating the face from different angles in infrared so the camera can create a depth map. None of that needs a secure connection.

It makes the phone parts next to worthless on the secondhand market, making it not worthwhile to steal the phone and sell it for parts.

Hector Martin has some nice rants about right-to-repair zealots and their lack of understanding as to why Apple made the decisions they did.

I can assure you that stolen iPhones absolutely aren't worthless. They are sent to various places where extremely technically sophisticated groups are still able to make at least 200$, sometimes much more, from a stolen iPhone, which isn't much less than what it used to be worth. In fact, phone thieves in many places only ever made about 50-100$ from a stolen high end phone.

Phone theft is a billion dollar industry, and as Apple tries to lock down parts, thieves adapted by forming far more efficient logistics and by centralizing value extraction from stolen phones. Apple's tactics haven't so far made a big impact to a phone thief's incentives, and I don't see it happening in the near future either.

I agree with the zealots but there could be better ways - for one, make the replacement screens "unpaired" by default, maybe using a WORM to store keys, so people (or repair shops) could still repair their phones with legit replacement screens while "second hand" aka parted-out displays would still be impeded.

You will own nothing, and you will be happy. :^)
