i've had coworkers complain about health checks only looking at http response codes.
i'm undecided. i think it's reasonable for proxies/load balancers to work at the protocol level, but i've definitely been hamstrung by it when working with libraries that don't always provide access to the protocol levels without combing through and learning the entire library.
how hard would that be to add? i guess there's not much overhead involved seeing any sane admin runs health checks at most a handful of times in a 3-5 second period.
