Martin, I agree it doesn't make much sense on the camera side of things except to state the range of compatibility. On the lens side of things, KAF3 means that it won't AF with a KAF2 camera. When a camera is described as compatible with both 2 and 3, I assume it supports lenses with either shaft-driven and the SDM AF. I wouldn't expect PowerZoom functionality, though, which is what the SDM contacts were used for in KAF2.
Still with the reservation of having got this right myself... :-) If you look at the joint press release for the 55mm and 60-250, for example, the prime is KAF3 and the zoom KAF2, but both have SDM.
