I think when you look at it from a profit-driven lens, though, third-parties are always going to have to compromise on something to keep costs down in order to make a profit. Apple, historically, overcompensates on its parts and has higher tolerances so, in order for a third-party to be able to make replacement parts at significant enough profits, they need to be parts that don't match the OEM in quality or function, by definition.

Just look at screen repairs. Apple checks in software to verify the integrity of some of the hardware in screens and, in the past, it led to people being locked out of their devices when they were repaired with screens that had dummy FaceID/TouchID sensors.
