Maybe, the effort is small. Optical stabilization in each and every lens is what
I would call effort
Moreover, the invention described by the patent has potential. In continous mode, it could equalize shake more aggressively and over more extended periods of time than possible with a moving sensor or lens. E.g., when following a bird with a tele lens, the AF point could be nailed onto the subject and not loosing the bird while the viewfinder image is shacky as hell to keep the bird framed at all and each image is still made sharp by sensor shift. Of course, would need a panning detection...
But that's me again, thinking beyond the point which is reasonable

After all, it's yet another patent ...
This post of yours summarizes pretty much what I would like to see happening in the next Pentax "high-end" cameras: reliable, fast, accurate and lock-capable AF, especially when it comes to BIF photos.
Also, and perhaps even more a wanted feature: an AF capable of locking on the moving subject "towards the photographer".
I have missed quite a few "would-have-been-great" birds shots because I just couldn't keep the focus on the oncoming bird(s), either in AF-C and/or AF-S ... I tried manual focusing under such circumstances and the results were actually a bit better.
But, that could well be because of the photographer himself, right?
