The principal here is that engine RPM = Flow and turbine speed = flow. With a sudden change in engine RPM, you have a sudden decrease in engine airflow. With the turbo spinning at the same turbine speed this would create an overboost. Unless it is quickly regulated at the point by the wastegate. My point is: If the wastegate can react that quickly on the DCT, why does the drivetrain need to be babied so much in the 6MT?
