Unless there has been some change other than to MCAS, the manual trim wheels are still the only option to correct runaway horizontal stabilizers.
What MCAS added was that it could keep reactivating. You got what looked like runaway trim, stopped it, and a few seconds later MCAS would kick in again. Each cycle of this could end up accumulating net trim until you got into the high force region and could no longer manually turn the trim wheels.
In addition, I believe MCAS itself has been modified. I have not seen a clear description of the changes, but they might include additional redundancy, rejection of improbable data, warnings that there are these problems, warnings whenever MCAS activates, restrictions on how much it can change the trim, and a cutout switch for MCAS that keeps the electric trim functioning.
In the worst case, manual retrimming with the wheels is still the last resort. I have seen it suggested, by sources generally considered reliable, that (prior to the Max) the need for the manual trim has been so rare that its use is not part of simulator training for any 737. I do not know if that will change, but if so, it would seem to raise the question of whether pilots of earlier variants also need additional training in its use (I would guess that it is most difficult on the largest and heaviest variants.)
I have a vision of... dissimilar sized gears, or something...
