Insightful clarification.
It is hard to find reliable sources on this, I must say.
I base my conclusion for example on these excerpts from [1]:
> MCAS would trigger in narrow circumstances. It was designed “to address potentially unacceptable nose-up pitching moment at high angles of attack at high airspeeds,” Boeing told the FAA in a proprietary System Safety Assessment
(This doesn't specify whether it would be unacceptable for certification, or for certification under the same type certificate.)
> Engineers determined that on the MAX, the force the pilots feel in the control column as they execute this maneuver would not smoothly and continuously increase. Pilots who pull back forcefully on the column — sometimes called the stick — might suddenly feel a slackening of resistance. An FAA rule requires that the plane handle with smoothly changing stick forces.
(This seems to indicate that it would be unacceptable under the general FAA rule.)
