> The linked article says why, but to paraphrase, the training has always said to flip both switches. And the root cause reason for that is Boeing was hiding changes in order to make the same type certification.

It would have been safer overall to have a new type, and then they could've had a cut-out switch just for the MCAS and trained pilots on how to use it.
