Extremely.  By default dig asks for recursive resolution, and it has
no sense whether the target @server is a resolver or authoritative
server.  Most authoritative servers are properly not configured to
allow recursion, so when the answer comes back without the recursion
available flag set dig just makes a note of that.

You can use dig +norec to turn off the recursion desired flag in the
query, and that will make the warning go away.
