Completely agree!
However, as the pitot probes iced up the indicated altitude dropped by about 200 feet. The report suggests this is what led to the initial nose up command and someone who is unfamiliar with high altitude flight has potential to overcontrol in this situation (also: armrest in correct position? Seat all the way forward? All these things influence sidestick input - for me, half a turn on the angle adjust can be the difference between smooth flying and not).
