I don't think that is practical in action at all. Prior to docking the camera on the tripod, it is common to walk around eyeing the subject (with any format camera), and repositioning the tripod to that point. Nothing more should normally be necessary, especially nothing more with LF given the complexity and time needed to set adjustments. I've never ever needed to move the camera in a "fraction of a second": what's the hurry? If I need to tweak the image, and never quickly, I employ a tilt-shift lens, but that is entirely a separate matter to movement of the camera, which does not change.
