With omnis, I would agree with you. However, mecanums generate as much side force as forward/reverse force
by design even when the robot is driving directly forward. With octanum, I'd consider the traction wheels as having
less sideways loading under most conditions, probably only exceeding the peak mecanum side load when being T-boned. And in that case, the solution is to switch to mecanum and strafe your way out of the t-bone, or at worst into a legal pin that (under most years' rules) is time limited.
