I strongly disagree. the -09 wording:

   The client MUST fail to match a presented identifier
   in which the wildcard character is contained within a label fragment
   (e.g., baz*.example.net is not allowed and MUST NOT be taken to match
   baz1.example.net and baz2.example.net)

attempts to invalidate rfc-2818 through the use of "MUST NOT".
