It neatly avoids a lot of wasteful authoritative queries.
This is an interesting statement. Do you have any numbers on this,
oris this based on intuition?
In order to measure this, you would need to measure it on a fairly
active cache, not on the authoritative server.
my intuition is that treating nxdomain as a cache traversal ending
condition will have very limited impact on authority servers unless
those caches are also doing qname minimization.
