Is there any reason to believe, even in a wild scenario, that the CSC or an IFR has the remit, authority or jurisdiction to remove (or even recommend the removal) of a TLD (.ARPA or otherwise) from the root?

I assume that Greg at least understands the proposal well enough to pose this as a rhetorical question.

But in case anyone else is confused, the answer is short and simple: No.

The existence of a TLD  in the root is a policy decision my within the ICANN or iETF processes, CSC and IFR review only the performance of the IANA in implementing those decisions.
