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...).
