I much prefer the parts pairing that is required by Apple. Parts pairing is a mitigation to theft, but in my opinion should be a stronger anti-theft measure. I don't think Apple goes far enough with this. At the moment, a locked part, that is a part that has been taken from a mac with the activation lock still enabled, should render unusable on another mac, or at least show up in the parts setting as marked lost or stolen, and should at render as completely inferior to that of a genuine or authenticated part.

This doesn't hinder repairability, as you will find with the Macbook Neo. It just thwarts a secondary market for stolen Macbooks and/or parts.
