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?
