	So how to fill the gap?

	Ignoring for a moment the fine structure of +1 and possible other
	corner cases, and assuming that the Tier-0 zone continues both
	to be available for transfer and to be a delegation-only zone,
	the list of country codes could be built dynamically using the
	following approach.

% dig @ns-pri.ripe.net e164.arpa axfr \
  | awk '($4 == "NS") && (/^[0-9]/) { print $1 }' \
  | sort | uniq

	Perhaps it's worth considering desirable administrative constraints
	on the Tier-0 zone, in order to make some such method fornmally
	(rather than accidentally) possible?
