Despite my scepticism of the overall project, I find the above claim a
little hard to accept.  RFC 2052, which defined SRV in an
experiment, came out in 1996.  SRV was moved to the standards track in
2000.  I've never heard an argument why it won't work, and we know
that SRV records are sometimes in use.  Why couldn't that mechanism be
used more widely?
