You are right. I thought PyObject_GC_Track() can be used to tracked objects because PyObject_GC_Untrack() can be used untracked object. I think there is no enough reason for this asymmetry. Additionally, adding PyObject_GC_IsTracked() to public API will not bother future Python improvements. If Python changed its GC to mark-and-sweep, PyObject_GC_IsTracked() can return true always.
