Speculation.
If that were true, Apple would only require the replacement part to be verified, but they also require the device receiving the part to be verified. That's the "pair" in "pairing".

The "require the device receiving the part to be verified" is just a consequence of how it's currently implemented. There are ways to implement this without the need to do per-device pairing, but doing so in a secure way is quite difficult. I suspect they'll eventually remove the requirement to pair devices using system configurator, if only because this removes the need to have chat assistance with pairing. That's costing them money to have a call center, and they want to avoid it I suspect.

Is this based on first-hand knowledge? I'm skeptical on both fronts because I neither see any evidence this is what's being combatted, nor do I see the technical difficulty of being able to self-authorize your phone's parts to be used in repairs.
Sure it takes some engineering effort to get there, but I wouldn't expect it to be particularly challenging from a technical point of view. The phone is already linked to a user account, and the phone's parts are apparently already linked to the phone that's currently using them.
* Apple wants to make sure components in an authentic phone are not capable of being stolen and resold (this is a problem today, even with the pairing, although it is less valuable due to pairing)
* Apple wants to make sure that if you change components, that the replacement component is authentic
* Apple wants to make sure that if you change components, that the replacement component is not stolen
I can't comment on specific implementations, but allowing users to just re-pair devices in the current state would not allow the above 3 goals to be met. By restricting who has access to the pairing tools, they can achieve those 3 with the downside being obviously it leads to a crappy user experience for repair.
And brand new parts could lock themselves to the first device they're put into.
It wouldn't be ideal for repair but it would be much better.
As it stands today, you can already use any random components, you'll just get a pop-up telling you it can't be authenticated.
