There was a note in this Digest about future Mexican "area codes" of
the form 52x after U.S./Canada etc. (country code 1) has prepared for
the coming of NNX area codes (in addition to the existing N0X/N1X area
codes).  Since the x in 52x is not necessarily 0, wouldn't this nix
the continued use of 1+7D in some sparsely-populated NPAs?  It had
been suggested that, since there are a slew of NN0 codes at the head
of the list of NPAs of NNX form, some sparsely-populated NPAs could
disallow NN0 prefixes and thus continue to use 1+7D in lieu of having
to go to 7D or 1+NPA+7D for intra-NPA toll calls.
