Personal opinion is 1) new type cert with basic aerodynamic characteristics meeting the requirement without kludge add-on crapola like STS and MCAS 2) If FAA buys off on the kludge MCAS, then at least smooth the thing out and have some warning that it is acting and not STS. Good grief, 10 seconds of down trim and moving the stab over 2 degrees? Sheesh. Sure, if I was a "trim-aholic" I could beep nose up after one second of uncommanded nose down trim and keep doing it every 5 seconds. I could also ascribe the uncommanded trim to the STS, just as the previous crew in Indonesia accident sequence did. That crew may not have realized they even had MCAS installed, and simply turned off the electric trim motor, used the wheel and flew on. Oh yeah, no clear AoA failure indication and the single point failure and ......

You do realize there is kludge on crapola in virtually every airliner flying today.
