Your point on form drag is well taken, however since ground acceleration would be affected by total aerodynamic drag amongst other things, specifically in the crosswind case, let's say you apply no input into wind causing the upwind wing to rise as you accelerate surely you are creating more drag in this case.
I would even suggest that the correct amount of upwind control yoke input with resultant spoiler deflection allows the aircraft to accelerate more 'easily' up to the rotation point.
