Tube tool “un”validated branching

It may make a useful ZSpheres like tool if one could branch a new tube from an “un”validated tube node so that posable stick figures could be drawn. This would ideally result in a branched tube where all tubes remain “un”validated and posable.
It would be especially helpful if the tube curve nodes could have a parent child hierarchy so if a parent is moved using some sort of alternate gizmo selection/move mode that the lower child nodes move with the selected parent node as the pivot. The goal would be to leave the stick figure “un”validated and posable or validate it and use it as a base mesh.
