Why do Splines not have a DeformCache?

Hi,I am trying to get the points of a deformed spline here, so my plugin object can work with a deformed spline.
Everything would be so easy, if op->GetDeformCache() would not always return 0x00000000 when "op" is a SplineObject.
Now I have to use CurrentStateToObject and clone the spline including hierarchy (because if I use COPY_NO_HIERARCHY, the deformers are of course gone). The problem is: When the user puts my plugin object as a child object of the Spline, Cinema crashes. I guess, it's recursion. Sounds logical.
So my question is:
How can I get the deformed points of a spline without cloning the spline's hierarchy?
or
How can I prevent either that the user puts my plugin object as a child under the spline,
or
how can I recognize if the spline is a parent of my plugin object?There has to be a solution. But which?
Thanks for any help!!
Greetings,
