Well... This is *exactly* what happened at the 46th IETF (DC) interoperability
event, and perhaps at prior events as well.  The results are posted here:
<http://www.isc.org/interop/>.  Note the reference to the Perl config file
generator and the Perl master file generator.

Still, I agree completely that a protocol compliant server can exist which does
not parse zone files (we make one here at Cisco).  However, having a user
interface which does parse zone files can make life a lot easier, as it did for
me in this particular case.  I think BCP status for zone file format might make
sense.  I certainly don't see it as part of the protocol, but as an aspect of a
useful user interface.
