This one is really a case of awk vs. one-true-awk. It is a totally new
code base from a different author.
BIND 4 was originally written by the CSRG folks, as I'm sure many of you
know. It was an awful mass of spaghetti and became something no one
wanted to touch after the CSRG contract for BSD ended.
When it had become obvious that BIND had to be updated, Paul Vixie was
crazy enough to take the job. He worked on BIND and started on
reorganizing the code and bringing it up to date. But he soon realized
that he needed some backing and help. Enter ISC, founded by Paul to get
support to pay people to work on a real BIND re-write. The result became
BIND 8, although the same people worked on later releases of BIND 4.
Then came the Internet bubble and the need to update BIND again. Paul
decided that the best way to get people to work on BIND was to start a
company to write it completely from scratch with the financial backing
of the ISC. This was to be a clean re-write with no code from the old
version. The people writing the code were not to even reference the code
for prior versions. This was because Paul felt that some of the
copyrights were at least cloudy and a complete re-write would end any
issues. Note that BIND 9 has no BSD copyright notice.
So, even by David's standards, BIND 9 is different code from different
writers with a different copyright and ownership. And, as pointed out,
it has virtually nothing in common with bind.
If there is any doubt, we can always ask Paul V. for confirmation that
BIND 9 is a totally new code base. /usr/contrib/bind9 is clearly the
right place for this, IMHO.
