add mass center to rigify rig

hello, I have a suggestion about improving the rigify rig in a blender, so I propose to add the center of mass of the body to the rigify rig in such a way that by moving parts of the body this center of mass would also move according to the laws of body physics, this center of mass of the body can move and rotate and the whole body follows. this principle dictates character animation in stunt expressions. this principle is embedded in a computer program cascadeur if you would implement this in new versions of blender, I will be very grateful
