The XMLHttpRequest object can be used to request data from a web server. Without a method to obtain the cookie without having guarantees that the password cannot be transmitted or saved elsewhere, it would be ethically difficult to encourage other developers to use as a pattern in their app since it means encouraging the possibility to intercept passwords, which might be what the W3C imagined, and is of course what OAuth was made to address. I can understand the frustration with being unable to access legacy systems with what seems like small restrictions, but I also see W3C's intention on the other hand. That's exactly why limited platforms exists, so these worst cases can't happen. It is unknown if your request already includes withCredentials since you don't show any code in your question.
