This has not changed. (It could be fixed aerodynamically by
installing a slightly bigger HS, but that means more drag and thus
higher fuel usage. ...<br>

<p>If you've a choice between getting the physics right or fighting
it with your control system, you should, IMHO, go for fixing the
physics every time. It was, IMHO, a fundamental blunder for Boeing
to adopt MCAS as the solution to their 737 MAX attitude problems
(whether those problems were technical or cultural). Moreover, I
suspect that, given Boeing's current less-than-entirely-rosy
financial position (search the website of <i>The Economist</i>
for further details) the FAA is likely to have been under pressure
to accede to demands not to require solution of the problem in the
physics.<br>
