Lemme ponder that and check around to see if we explicitly said anywhere
that you were supposed to be able to keep old brigades after passing them.
My main concern is that if we keep your changes as-is, it might mean we're
constrained not to backport those changes to the APACHE_2_0_BRANCH because
of breaking backward compatibility.
