Yes, take the human spine for example: the double s-shape of the spine makes it very difficult to induce oscillations in it and helps absorbing shocks. And then there is the 'Dancer' robot (first example, ca. 20s into the video) with a straight 'spine' ... wobbling around. |

I assume Disney chose to separate the constraints by going with simple hardware shapes, yielding a predictable cost and an easy construction. A good hardware optimizer would also need to engineer assembly, which seems nontrivial.
Software costs of optimizing motion for existing hardware are more predictable (~19 minutes of an i7-7700 w/ 32GB, per second of animation).
That being said, they acknowledge in their paper that they could optimize certain properties of the robot, like rod size or joint position.
