I would suggest a fine-toothed audit of every single change made in the MAX aircraft, with particular attention paid to whether said changes were made solely in the interest of skirting regulations to sell more planes faster.
Because that is the point: Boeing's decision-making process is now highly suspect. It is pretty clear that the MCAS would not exist in anything like its current (flawed) form if Boeing hadn't been trying to avoid the pilot retraining requirement.
This is not a typical life-cycle for an engineering defect/flaw.
