Good. Thanks for considering this extension. It is indeed important to
suppress presentation of credentials even for same origin requests.

When the withCredentials flag is set to false, does it also issue an
"Origin: null" header? If not, then -- given the recommended server behavior
-- this flag isn't doing its job, since an identified origin header is still
a form of credential. As mentioned earlier, for credential-free same origin
requests, it would be adequate either to say "Origin: null" or to leave the
Origin header absent.
