I also just checked, and RFC 5280 specifies the rules for RFC 1123
regarding host names in certificates.  So even if we did accept this, no
publicly trusted CA could issue a certificate for such a domain, because
to do so would be misissuance.  So this at best could help people who
are either using plain HTTP or an internal CA using broken tools,
neither of which I think argue in favor of supporting this.

Or people using a wildcard certificate.
