Except for spool-up/down torque. This one is mitigated in some designs by using contra-rotating spools. F119 is one example. And honestly, I don't have an idea whether this torque is of relevance in reality. Does anyone here?
I am aware that in fighter jets, the motivation behind contra-rotating spools is to reduce their gyroscopic moment, and perhaps increase efficiency.
