At component level, yeah no impossible but for general resale it wouldn't be too hard. I'm pretty sure the Face ID and Touch ID modules already do this.

You would need to add some general identifiers to parts with a GUID and at production/official repair time, register those parts to an iPhone S/N. If Activation locked, those parts would need to not be able to be registered to another iphone until the original device is unlocked, thus clearing those parts.

Look - I get that it's probably not too hard to do with most of the parts that contain active electronics, but the comment I was replying to said all the parts.

How are you going to lock down the phone body? Or the screen (not including the digitizer)? Which, coincidentally, are probably the 2 most damaged parts of a phone.

I suppose there's probably some way Apple could lock them down. But that seems like an expense wildly out of proportion to the potential benefit.
