Substantively, I have only two comments: That peak sharpness will occur at exactly rather than approximately the same aperture.

It's not actually quite true, or at least, always quite true - because the system MTF is the convolution of the lens and camera MTF, and the MTF of a birefringent AA filter can, I believe, be a bit aperture dependent. But in reality, such an effect is too small to worry about.
