There is nothing wrong with spinal rotation as long as the motion is within the limits. Using the rotation at ankle and hip can greatly add range and power to the body rotation. Without them it's possible to overwork the spinal rotation. Injured back is no fun and it affects the whole mobility so it's wise to be cautious but spine is wrapped in many many muscles and some are very strong so you don't need to underestimate its functionality, but strong and flexible legs will protect the spine from overworking or pushing out of the range.
