The camera mechanical shutter delivers shock, but that happens all too quickly for IBIS, which is designed to handle human movement which happens a lot slower.

You are likely right for IBIS but maybe not for lens based IS.  A good many years ago, I investigated the IS in some Canon lenses (like the 100-400 L) on my 1D IV camera.  In particular, I found the bandwidths of the IS systems and found that they included the bandwidth of the shutter shock.  Since the lens system does not care where the motion comes from, I concluded that the lens IS was able to correct for at least some shutter shock motion.  My experience with my lenses seemed to bear this out.  Motion of a small lens element in a lens can likely be rather quicker than moving a sensor.
