replacement for CylinderSpatialObject?

ITK 4 had CylinderSpatialObject. However, this was (silently?) removed in SpatialObject Refactoring for ITKv5 · Pull Request #613. Is there a replacement for it?

Maybe TubeSO? @Stephen_Aylward can probably advise better.

Yes - a cylinder is the same as a tube comprised of two points. If this become challenging for you to update your project to this new representation, please let me know. We would easily bring back the cylinder spatial object.
