You've obviously missed the point of my concern, which is code bloat.
A parallel set of functions incorporating B-M would make things worse
not better from that standpoint. (Unless you are proposing that someone
do it as a separate pgfoundry project; which'd be fine with me. I'm
just concerned about how much we buy into as core features.)
