World particles collider scriptable?

Sorry...no answer.
I've just had the same question and after some hours of testing. I really think it's simply not implemented and we can't access the parameters.
But it would be nice to hear something official about this issue.

My last test...

     Debug.Log("-> [WorldParticleCollider]");
     object wpc = (object)gameObject.GetComponent("WorldParticleCollider");
     Type typ = wpc.GetType();
     Debug.Log("-> Type: " + typ.Name);
     Debug.Log("-> [Members]");
     System.Reflection.MemberInfo[] mem = typ.GetMembers();
     Debug.Log("--> Count: " + mem.Length);
     foreach (System.Reflection.MemberInfo nfo in mem)
         Debug.Log("---> " + nfo.Name);

...spits just out the standart component parmeters.
