So any extra depth beyond allowing your fiber optic to sit on the "shelf" at the bottom of the rear sight is excess and not desirable?

I see a lot of competition sights with very deep rear channels, and some with much shallower rear sight channels. I think I understand what the pros/cons are of the width of the channel and the width of the front sight; however, I can't find much on how the depth of your rear sight channel affects your shooting. It seems to me you would want it as reasonably shallow as possible to avoid vertical stringing of shots. What are the pros/cons of deeper or shallower rear sight channel depth?
