Yeah, I think that's a tradeof past it's days. I'm all for nuking it,
and while we're at it we should also find a better way to integrate the
mpage bits. Not using them is pretty dumb, so the default aops should
really be mpage if possible, else fall back without the need for
different sets of aops.
