Yes, you are right with that, but there are two issues witch this
configuration :
1/ The private WAN between local DNS and central DNS would become
critical, even for local Internet access, which is probably not a good
idea. Of course, one can setup forwarding to try central DNS first, then
local ISP's DNS or ROOT server.
2/ The private WAN might become overloaded with DNS queries, causing
delay for local Internet access.
Anyway, I don't think I will be able to argue with local DNS admin,
telling them to query a central DNS in France to resolve anything from
all around the world. (Of course, we all know that the DNS used to
resolve might be anywhere in the world, but...).
