vtkNew move semantics

What are the odds of getting move semantics on a vtkNew object? Because the copy constructor and assignment have been explicitly deleted, that has dragged move semantics along with them. That makes the vtkNew class a not-quite unique_ptr making passing ownership impossible. I'm contemplating creating my own local version of vtkNew that has such semantics (and yet calls object->Delete() to otherwise maintain compatibility with the VTK garbage collection). It would be nicer if vtkNew were truly a VTK-branded unique_ptr.
