IIRC, the issue was that we'd painfully hammered out a set of preferred
I/O behaviors for the inet and cidr datatypes, and then hacked up the
code we'd imported from BIND to make it happen. Paul Vixie sent in a
patch that replaced the imported code with v6-aware BIND code ---
thereby reverting those painfully-agreed-to patches. So it got
rejected.
I have no problem with restructuring our I/O behavior as wrappers around
the pristine BIND routines; although privately I doubt it's worth the
trouble. The really interesting part of upgrading to v6 inet support is
going to be obtaining a consensus on how our current I/O behaviors should
translate to v6 addresses. Once we have that, I suspect that slash-and-
burn mods on the BIND code will again be the way to go ;-). It's not
like v6 is going to be replaced in the foreseeable future.
