We have to wait and see how the new AF system performs in the field.
FYI, Nikon also officially support AF at f/5.6 only, but they do not "disable" it at smaller apertures, they just don't guarantee reliable operation. I think Canon was paranoid with giving you something they were not fully confident in and having people complain to them later.
