Good catch. WKS would then probably need a separate document that would also remove it from RFC 2136. But it’s funny that we should not remove a record while this was already written in 1989: An application SHOULD NOT rely on the ability to locate a WKS record containing an accurate listing of all services at a particular host address, since the WKS RR type is not often used by Internet sites. To confirm that a service is present, simply attempt to use it. While the special processing was added to RFC 2136 (9 years later) is really beyond my understanding :(.
