I have seen feature requests in the past that when haproxy reloads, to pull the health status of the servers so that haproxy knows their state without having to health check them. Willy has said he liked the idea (http://marc.info/?l=haproxy&m=139064677914723). If this gets implemented, it would probably be a minor detail to not only dump the up/down state, but all stats.
