Yeah, there's no pointing to other hosts in WKS, just information on the host itself. I believe it come out of ideas about service discovery in the early days of the internet, when you might know of 100 other hosts, but not know which ones ran SMTP, FTP, etc. The WKS records would let you get a map of the net's services by doing a bunch of DNS lookups instead of having to portscan everyone. SRV records are more like an MX record generalized to arbitrary services, allowing a domain to point to the hosts that provides various services for that domain.
