For 1/16000 to expose properly at F2.8 or lower you would all but have to point it directly at the sun. In this case, you are just an idiot for pointing your lens at the sun and deserve for your AF sensor/mirror box to get melted. Generally you only want a fast aperture outdoors for doing portraits of people or animals. In these cases you don't ever have that much light on your subject. If you did the subject would be blind. For most outdoor shots where you have the sun in the frame you tighten down the aperture to sharpen up the lens, get better DOF and so that the sun gets that cool shinning star effect.

In any case, clearly Canon felt that 1/16000 was a useless spec as it has not been seen on any of their pro cameras since; and you don't hear anyone complaining about it.
