AFAIK the airflow or AOA does not vary directly with speed, only pitch adjustments can vary those. The problem with adding thrust with underslung engines (not just the MAX), is this tends to produce a pitch up moment. Adjusting both pitch and power at the same time requires some training, to avoid a delayed stall recovery. With propeller engines and fuselage mounted jets, this effect is not a factor.
