Those movements just happen to be slow enough that they don't limit image stabilization to 6.3 stops.
Under what definition the Earth's revolution is "slower" than its rotation?
Why can the camera's stabilization system detect the rotation and correct it (and causes undesirable result) but not the revolution?
As far as taking pictures of other things on Earth, at least. Taking a picture of another planet/star/galaxy would also face similar challenges.
The next level of stabilization would probably be gravitational waves.
