Am I misunderstanding what you're saying here Ken or are these two statements contradictory?
All of my AF lenses focus at max aperture, then stop down to take the shot (speed of focus is one of the reasons I went for f2.8 over f4 for my 70-200).
I can't see, in that case, how being stopped down will have any impact on "visibility" for focus points.
