i've had my symbolics 3640 online quite a bit in the last 30 years, and 
it still makes WKS queries, and i have used WKS responses to control it. 
the software still works as well as it was designed to do, but the 
vendor is long out of business. however, read on.

please see down-thread where deprecation turns out to be both 
undesirable for the reasons i've given, and additive to developmental 
complexity since there would be _more_ DNS RFC's to read, and suboptimal 
compared to declaring a core subset of DNS technology as "mandatory to 
implement" and simply leaving WKS (and its hypothetical friends) out of 
that core subset.
