I think the more germane question is whether anyone actually realized that a single-point failure had been introduced into the design after all the modifications. It appears that there were too many chefs with a hand in the MCAS design and no one stepping back to give it a thorough top to bottom review. We would like to think that during the design phase someone would have seen what has now become obvious to everyone, but given the time pressures and compartmentalization built into the process, I can also see how this might have been missed.
