Re: [fetch] Status code to use in a response indicating rejection of a cross-origin access (#172)

Oh, wait -- are you talking about a status code to be generated *by* fetch if there's a cross-origin access failure? If so, 403 is definitely the right one; it's not restricted to use on the origin server. You can add headers (or body) to refine the semantics if you like, but a new status code isn't necessary.
