Under MCAS 1.0 the linearity would be preserved, because the system could fire a second time if the pilot continued to pull up. With MCAS 2.0 this repeated triggering can no longer happen during a single event (or so we are told). If the crew continues to pull up (for whatever reason) they are effectively entering test-pilot territory.

The response may be linear the first time, but definitely not for sustained maneuvers. This was true very early in the discussion, and remains so. No half-cooked computer system such as MCAS can be safe, effective and reliable, all of the time.

Loose rivets I think this is more a reaction of disgust than alarm. All the attention is implying that the system is almost ready, and we can soon move forwards.

The recent comments from across the spectrum seem to emphasise that nobody is truly happy with this band-aid/kludge/fix, and that the aircraft/manufacturer/regulator are permanently tainted in the view of inquiring minds.
