It is possible Ether is right, but I will need more convincing than can be done without a practical trial.

To my understanding, yes, a portion of the force exerted by the mecanum wheel is not used in moving the wheel directly forward or back. Because the wheel exerts force at a non-zero angle in reference to the forward/back direction, a component of the force is going sideways. However, the component of the force exerted in the forward/back direction is identical to the force exerted by a regular wheel in the same system.
My point being that yes, some force is "wasted" by the mecanum, but it is a sideways force
The mecanum puts out the same force as a regular wheel in the same direction.
