Hmmm. That doesn't make sense to me. If your threat model is someone swapping parts, surely someone will sell you a genuine or counterfeit part. The buses aren't actually encrypted, so you can still just hijack it. Sorry, but Apple's stance on this is not security, just $$$ in disguise. The same can be said about all their "privacy" things, they just want the data themselves so they can sell you more stuff and their competitors can't.

It most definitely is security. It's not a matter of "genuine or counterfeit". The two components (secure enclave and touch id/face id sensor IIRC) are cryptographically linked. If you switch the touch/face sensor to a counterfeit or even a genuine part, the secure enclave won't recognise it any more and won't unlock. You need to be able to re-link them cryptographically and Apple won't do that because it's a gaping security hole. The damn FBI couldn't crack it on the iPhone 7 and had to go another route. If it was just "$$$ in disguise", why was it so effective half a decade ago?
