Well, the idea to attach FQDNs to services, not to computers, is pretty
sound; and could (if implemented) concievably replace lots of ad-hockery
like MX RRs, "virtual" HTTP servers, etc, etc.

WKS RRs weren't doing that - the boundary between host names and service
names was still in place; so WKS RRs were simply redundant.   Following
the logic of lazylution they quietly died off.
