> There was a safer configuration as an optional extra purchase; Forgive me if I'm missing something but these extra options are AoA cockpit indication and AoA discrepancy alert when two sensors disagree. They don't alter software, MCAS would continue relying on just one sensor regardless of this indication. It's just an extra bit of information for pilot's decision making. Sounds to me like another hack over the hack hardly adding much extra safety.
