The state loader (vtkSMUndoRedoStateLoader) takes over the
responsibility for loading state for an undo-set since it needs to
create the right type of undo-elements etc. Hence there's no default
implementation provided.

I see that vtkUndoSet::LoadState() is just a virtual "stub" method.
The comments preceding this method in the .h file say that subclasses
are welcome to override this method to provide functionality. Are there
plans to provide a default implementation in the vtkUndoSet base class,
in the future?
In other words, is this a conscious design choice, or just a feature
that has not been implemented yet?
Thank you for any clarification you could offer!
