[dns-operations] operational impact of empty MNAME and RNAME?

[Joe Abley]

Hey,

For a zone which definitively doesn't support dynamic updates, the  
MNAME field in the SOA RDATA seems extraneous.

Similarly, adding an additional stream of spam by putting real data  
in the RNAME field seems to verge on the pointless.

Has anybody tried hosting a prominent zone with these fields empty  
(e.g. specified as "." in a BIND9 zone file)? Was there any negative  
operational impact?
