<https://github.com/httpwg/http-extensions/issues/3410> A specific status code needs to be selected. The initial draft suggests one in the 4xx range. That seems to be appropriate given the semantics desired (whether broad or narrow; see #3409). If that holds, we should select a code that is unregistered and relatively unused. The next unassigned 4xx status code is 419. No use is documented in MDN or wikipedia, but I see a few resources that mention a single PHP framework is squatting on it to indicate that a session token is expired. What do people think?
