If we knew, we'd do it ;-) But no one's put enough effort into it
to find out.

Yeah, we finally gave up on rtree entirely. I don't want to see any
other index AMs languishing in the closet like that. If bitmap can
hold its own to the extent that people are interested in working on
it/improving it, then great, but I'm worried that it's not going to
have a wide enough use-case to attract maintainers.
