Which leaves me with "why is BIND 8 still part of NetBSD?"

Invalid reasons include "it's proven"  (yes, and orphaned now too)
It's not longer supported; it's missing several Good Things.  BIND 9
*is* slower (bind 4 is fastest, djdns is next, then BIND8 then BIND 9).

If you're not doing mail blasts or running AOL's DNS, you likely
don't care (and frankly, if you are, a 4CPU machine with 8GB of
RAM will perform better with BIND9 and still costs less than a week
of a really good consultant).
