Interesting situation that the regulators and Boeing find themselves in, on the one hand MCAS is needed because without it you could in extreme circumstance be unable to recover the aircraft from an UAS and yet if MCAS malfunctions with the current software it might put you in an UAS
Choice seem limited to "trusting the new software to be sensor failure redundant" or a massive redesign which would probably result in it being a new type rather variant or scrap it and build a new aircraft from scratch ..............
I'd go with the software personally and more detailed sim training.
There is no way to switch off MCAS without disabling the STAB and trying to manually trim the stab in a high speed high work load situation is far from easy
