In the upcoming 2.0 is ungrpc an protobuf available.
http://git.haproxy.org/?p=haproxy.git;a=blob;f=doc/configuration.txt;h=40424073e58048100f79d08963e49d614a6e7dcb;hb=HEAD
Maybe this will do what you want
The `grpc-status` and `grpc-message` headers are passed as h2 trailers.
They're not in the protobuf body.
