Software would presumably be programmed with those limits to not break stuff. During normal operation, every gear in a differential holds the whole drive torque anyway. So really the only issue is sudden changes in wheel vectoring which could end up using engine/driveshaft momentum to smash gears. You'd just program the software to not do that.
