i don't see why it couldn't be. i don't think it's against spec to
have a generic function when it doesn't specify one.
if i had to guess, it's not because it started out as a simple wrapper
around file-stream-external-format. the etypecase was added later
when broadcast-stream support was added.
unless there are objections, i can rewrite it as one.
(defgeneric stream-external-format (stream) ...)
(defmethod stream-external-format ((stream file-stream)) ...)
(defmethod stream-external-format ((stream broadcast-stream)) ...)
