My idea is that the mechanism is implemented by the user, and the ODE
provides only a plug-in function call in destroy functions and a third
cleanup mode with conditional destroy (with user specified "plug-in"

My idea is that API doesn't change at all because it is the user who
implements the feature. The only change is the third cleanup mode and
two function placeholders. And in implementation, a pointer stored in
relevant structs (dxBody, dxJoint and dxGeom) passed to these
