   This is a bit more nuanced - when status code, headers, and body are all missing, the sensible default is clear. But what if only some of those values are specified?
   
   As in a status code is specified, no body and no headers? This can lead to content negotiation errors.
   
   Or a body is specified and no headers? Should we infer JSON type for example? This is something we considered useful to avoid base64 encoding an http response.
