I guess the question is whether we prefer adding this information
into the response header and having clients do the request-and-terminate
trick, or defining a well-known endpoint servers can implement which
takes a path as an input and returns either what the response header
would be, or maybe a small JSON structure of metadata (which could
include stuff like last-modified date).
