Which goes back to one of the standard-provided definitions of domain name syntax used by RFC 821 page 29:
RFC 821 defines the syntax for mail domains, not domain names in general.
RFC 821 hostnames are not the convention for Domain Labels, esp as we enter the age of Non-Ascii labels.
Host names are not mail domains. RFC 952 defined the syntax for host names. RFC 1034 recommends that labels in the DNS follow either 822 or 952 syntax (which are mostly the same). All of these were updated by RFC 1123 to allow leading digits. Internationalized domain names do not affect the restrictions on the syntax of what is put in the DNS.
