Agreed :)

DNS is suppose to be 8-bit clean as according to RFC 1035. But taken
in context with that recommended section in RFC 1035, together with
RFC 952, many legacy implementation already assumed DNS must be LDH.
By the time RFC 2181 comes along, it was too late.

This was one of the reasons why Punycode was chosen and not UTF-8 for IDN.
