I think what is missing in this picture is that Boeing purposely hid this system as far as pilot training and understanding of it to save money for the operators and in the end, Boeing.
It gave the crews who encountered a problem nothing to work with or understand in order to deal with it. A highly experienced crew may have been able to handle it it just fine, but that is not the smart or safe way to handle a new aircraft.
This is a huge problem because the bean counters have too much influence in their operations.
