Scalar variables would also work since of course at the end of the day all we need is extra rows with which to impose the constraints. However, the reason I prefer an "isolated node" is that I already have code for imposing these types of constraints between "non-isolated nodes". That code works seamlessly with isolated nodes too, whereas using SCALARS would require separate code paths for isolated vs. non-isolated nodes. Also, given that we already have NodeElem and Exodus has SPHERE elements, I don't see any downside to that approach.
