There have been plenty of motorized lenses in the past that relied on the micro-contoller inside the camera body for control. What does having the controller live on the lens permit that the pattern we've used for years doesn't afford?
You don’t _have_ to update lenses. The updates pretty much just fix edge case autofocus issues usually with specific cameras and settings. Before update mechanisms you just had to deal with it or buy a new lens.
