They also need to either add a manual MCAS cutout (separate from the power-trim cutout) and probably add a third AoA sensor too. The airplane will not be safe as long as the only way to exit a nose-high MCAS runaway situation is to cut out the power trim and move a wheel that physically cannot be moved while the aircraft remains in the nose-high situation. And without a third AoA sensor the chances of a failure remain unacceptably high.
