I'm not sure. I seemed to believe in that thread that they could never be NULL, but I'm not sure if everyone agreed, and I see that we suggested a non-NULL tag on objects somewhere. So, in that case, there may be no difference at all to the middle-end. In any case, I think that it would make sense for us to allow a REFERENCE_TYPE anywhere we allow a POINTER_TYPE.
