You have a point, though, from what I have read, I do not think the airplane would become unstable prior to the stall, merely less statically stable than its predecessors. Boeing may be denying that MCAS has a stall prevention purpose only because to say so might put it in the critical systems category, requiring additional training. If so, this would apply as much to the fix as it does to the original version. To acknowledge that it has a stall prevention function might require an additional AofA sensor as well as additional training.
