That seems pretty reasonable.  It would be introducing a single point of 
failure where one need not exist.

[a light goes on]  Ahhh, I'd never considered that.  My own nameserver will 
quickly cache, say, the MX record for isc.org while my neighbors probably 
don't want that information.  That makes perfect sense and seems like a 
good enough reason on its own.

I appreciate the reply, and I'll try to point others to it when it 
(inevitably) gets asked again.
