are numeric string representations now, after 30 years
going to be outlawed? if so, on what basis?
?
I'm suggesting that there are technical reasons why strings comprised
of all numbers and those that start with 0x and contain hex digits
should not be TLD labels.
In theory, the limitation against all-numeric/hex TLD labels should
not need to be made. However, in theory, a label can support any
octet value between 0 and 255 yet the IETF has gone to great lengths
to greatly limit the values within "hostname" labels...
