RFC 1123, Section 6.1.3.2 Transport Protocols, introduced the SHOULD with
the current well known description.

         *    "SHOULD"

              This word or the adjective "RECOMMENDED" means that there
              may exist valid reasons in particular circumstances to
              ignore this item, but the full implications should be
              understood and the case carefully weighed before choosing
              a different course.

If you read that along with Section 6.1.3.2 I don't see how any
vendor could ship a recursive DNS server that doesn't support TCP.
I can understand how you could ship a authoritative server where
you have full control over the data you are sending.
