The puzzle to me is why you would be puzzled.  Maybe you are noo looking
at the same code; the code I see looks like this:

                if (((status = response(NULL)) / 100) != 2) {
 /* ................ irrelevant lines omitted .................. */
                        if (retries < 1)
                  "Can't read news info. News host %.20s responded: %.200s",
                                NewsHost, response_text);
                        return HTLoadError(stream, 500, message);

There isn't any return(status) in there.

I think you wouldn't like the outcome if HTLoadNews() *did* return 421.
See the bottom of HTLoadDocument() in HTAccess.c.
