I don't think it would be too difficult for Canon engineers to do.
Allthey have to do is design a lens so it reacts in a certain way to
certain inputs from the camera, but to only implement these signals on
later bodies. This way third party engineers don't know that the lens has
to handle these inputs, as no current bodies send these signals. But
newer cameras do, so these lenses stop working properly, while Canon
lenses continue to function. But as I said, nobody knows if this is true
or not.
