I'm guessing this is the same anti-feature-creep sentiment as why
round-robinning RRs was left out of NSD.  This is unfortunate, because very
few clients bother to use anything but the first IP returned by their
resolver.

This would not be true if cnn.com were served by NSD.  The ordering would by
the same, every time, resulting in at least 3x the load reaching the first
IP in the zone file.
