That seems operationally equivalent, in the same way that sink.hopcount.ca doesn't exist. The philosophical difference is that (it is proposed that) SINK.ARPA be guaranteed never to exist, whilst it's conceivable I suppose that someone could one day propose a use for 257.in-addr.arpa and descendants.
