The http-wg mailing list is slightly better, but I consider www-talk
to be an appropriate place too.

The client should only redirect when getting a 3xx response.  If a
location header is present in another type response, the client can
either ignore it, or input it into some mechanism not covered by the
http specification, for example an extra navigation button in the GUI
in case of a 201 response.

The client should *not* treat a 200 with a Location as invalid http.
The general rule for http clients is: if you see some header you never
heard of, you can ignore it and process the rest of the response just
as if the header was not there.
