We (.jp) have probrem in this feature.

a.dns.jp and g.dns.jp (.jp's NS) are logging and archiving querylog
always in a long time. (since 2004, of course, we need huge storage.)
And we are using the log for researching and analyzing the state of DNS.
Latest work is in the OARC Spring 2013 Workshop.

  "Increasing DS queries for JP DNS servers
     and a proposal for its countermeasures"


During reflector attack, the querylog is increased. But state of RRL,
drop and stop are more increased of querylog. We would like to record a
querylog in reflector attack. However, we do not want to record the
state of RRL on the same querylog. It is the last option that we stop a
querylog. We want on/off feature of the state of RRL or logging
different from a queries category.
