Mostly unnecessary for nameservers, since as previously mentioned RTT 
(round-trip time) values are used for nameserver selection, if 
available, and is tracked by IP address, not by nameserver name.

That may have worked at one time, but not for anything that conforms to 
RFC 2181 (published July 1997), Section 5 ("It is meaningless for two 
records to ever have label, class, type and data all equal - servers 
should suppress such duplicates if encountered").
