That sort of thing is a bad idea, because you might get left with
old binaries still kicking around when binaries move. Remember the
upgrade problems people experienced when we moved nfsd from /sbin

That's a nice thought, but that confusion is a much smaller price
to pay than deleting unique user data on some ocassions is. Also,
you don't know, when pkg_delete is run, that a pkg_add isn't going
to be run right after to put in the new version of a package!
My rule is that pkg_delete should *never* delete anything that
pkg_add did not add. If /etc/named.conf was added and is still
exactly the same (same MD5), I could see removing it. If it's
different, that is no longer a file that pkg_add added to the
system, it's a different file that someone else put there. Since
someone else put it there, someone else can delete it.

Because I don't edit and change my binaries.
