It's not, separate, one drives the other. Their efforts to make the plane "identical" to the 737 in terms of training is what caused them to add these dangerous "features."
This is nothing to do with training. We are just talking about the location of two wires deep within the body of the aircraft.
The 737 has always had wires in this location. The original 737, the 737-Classic, the 737-NG and now the 737-MAX.
But the rules changed after the 737-NG was certified due to two major crashes. All new aircraft designed need to meet these new rules, but old aircraft designs get grandfathered in.
