Why not add head motions to the game (especially for cinematics)?

I don’t mean ones where you have to click any buttons to move the head up, down, left, right, or use VR to do that. I mean when moving your cursor (the circle), and especially when moving your HUD. Along with having this, the head/body could move with the G-forces of the aircraft. In my opinion, this could add to realism for anyone making cinematics or maybe just in general.
