Why would this be so valuable compared to basic HTTP health check?

  If you've got a gRPC API, you don't necessarily have anything serving HTTP that would correlate to that service - I know we don't, for example; the only HTTP is for serving static files, everything else is gRPC, and HTTP checks wouldn't spot any problems.

    Don't people usually use gRPC over HTTP?

      The core protocol uses HTTP/2 as a transport, yes, but you'd have to convert the conceptual gRPC request to the protobuf-encoded version and somehow pass that to the HTTP/2 endpoint as a binary blob, then decode/match the binary blob you get back - which none of the status pingers really offer either. (You could use `gRPC-web` to make JSON-encoded requests but you need specific support on the server end for that.)
