According to the link, Doug Barton made the changes on June 18 to start
slaving the root zone. I think he's on this list, so he could probably
comment more on his decision.
I know this argument has happened before in other venues, so I am
hesitant to join in, but it occurs to me that if we believe that there
is a significant amount of garbage traffic (for local zones, RFC1918
resolution, or just bizarre crap), then slaving . might actually benefit
the root nameservers. OTOH, if your nameserver is only sending legit
queries to the roots, then you're probably not helping that much by slaving.
Moreover, I run a caching NS on my home FreeBSD workstation, which
averages very few queries per hour over the course of a day, and I have
a hard time understanding how it or the root NSes would benefit from
having it slave root.
