Surely, Boeing need to remove the MCAS system by reverting the 737 design to
be stable rather than unstable.

The 737 MAX is, as far as I know, the first commercial airplane to be
unstable. All military fighter airplanes are unstable but that is a military
fighter. To date, again as far as I know, the strategy had been that all
commercial aircraft were stable. Boeing broke ranks on this strategy with the
737MAX simply because they were trying to put an engine that was too big for
the space available and so moved the engine forward and upward creating an
aerodynamically unstable configuration.
