With fear of putting words into Bart's mouth, perhaps he's saying that
the BFQ is a bit of a mess and it'd be nice if we had a cleaner version
of some of the features it brings. But having someone actually maintain
it and perhaps clean it up a bit and reduce the complexity would be a
good thing. Really it's the authors choice on where to best spend his or
her time.
