The touch bar could have seen use as a true "SAK", providing a direct, trusted I/O path between the user and the secure enclave. I was always hoping we would see interesting security features out of that capability. But the killer use cases never seemed to materialise and touch bar does not seem loved enough to justify extra BOM cost. I do wonder what % of this move is UX and what % is cost optimisation.
