(IMO) It's not realistic or practical to change the MA setting every time you change the aperture when you are out shooting. And it's most important wide open where you have less DOF than at any other aperture. If there is a large difference on the lens at different f-stops, maybe Canon should check and adjust it for you.
Let's say we're talking about the 50L here, and let's say for several reasons I shoot it almost exclusively at f2. In such a case, wide open MA is pretty much irrelevant and indeed wrong.
