because i am loathe to break existing working configurations. when isc 
changed the value of allow-query to be LAN only, it took years to do as 
safely as we knew how, and even so there was some breakage.

we don't see a lot of intranet data, so that would not be dispositive. 
however, i urge you to reconsider your strawman-ish feelings. we are 
forever rebuilding the airplane in flight. the long tail matters.

as long as people know what they're doing and are willing to convert 
their zones using tools unspecified, that's true. but you are chewing on 
the narrowest part of bert's camel here, at some risk, little gain.
