ACK as long as it doesn't mess up migration (I guess we need to find
some config that already works, but changes the ordering with the new
code, and make sure it can be migrated from old->new. Or we could assume
that 1) we believe it isn't a problem, and 2) in practice most things
that would be re-ordered wouldn't have worked at all without the
re-ordering, so it's a non-issue).
