I doubt it would have been "out of control", it would have just been slow changes over time as trim increased. The pilots might not have been fighting it much either, if they thought that airspeed was the problem, and not pitch.

The graph on page 14 of this report[0] is pretty telling about how slow the changes were... Note Trim Manual, Trim Automatic, and Pitch Trim Position.

Thanks! Page 23 of the PDF or 14 as printed at the bottom. Sadly it's hard to compare with the previous flight (pg. 25 or 16) as for it they published the graph of the whole flight instead of only the part until the (at the time still secret) MCAS was turned off (or probably more correctly, the motor controlled by the MCAS, which actually steered the "trim").
