At some point the various regulatory agencies will need to figure it out.
FAA needs to require Boeing to remove this "speed bump." That some alert and competent pilots are able to overcome it is wonderful, but still an insufficient level of safety as attested to by hundreds of fatalities. If it turns out that AoA sense system failures are the root cause of the MCAS behavior, then the AoA sensor system needs to be made more reliable (higher integrity), in keeping with potential catastrophic failures.
