Most people acknowledge the effect, and use it to their advantage. If you cant the head a thousandth or so, the trailing edge of the cutter doesn't touch, and you get a smooth surface. Granted, there is a slight concave effect on the surface, but with a minimum cant, and a large sweep of the cutter, it is usually within acceptable limits. Most things that must be truly flat are ground and/or lapped anyway.
