Well, here is how I see it. Since Hablis is not a single creature - but a mixture of creatures - it can't be an ancestor and therefore is an
invalid category for transitional status. With Hablis gone, there is no clear cut transmission between the Australopithecines and Homo Erectus.
That makes no sense at all. If the specimens assigned to Homo Habilis in fact belong to two different species then one - or possibly more - of thenm still could be our ancestors. A dispute over classification in no way changes the fact of the specimens existence. And if you had read you would see that habilis is NOT gone - it is simply proposed that some of the fossils currently assigned to habilis are assigned to other species instead.
