I am trying to use the hosted version of jQuery in a user-script, but since Google Chrome runs user-scripts in a sandbox the only way I am able to include jQuery is by copying/pasting the minified version or loading and evaling it using an xmlhttpRequest. Using xmlhttpRequest seems like a better way to go since it will make the scripts smaller and often already be in the user's cache, but Google Chrome also restricts xmlhttpRequests using the same-origin policy, so I would need to either host it on the same domain as the website (not feasible for user-scripts) or use a CDN that includes the 'Access-Control-Allow-Origin: *' header defined by the W3C Cross-Origin Resource Sharing (http://www.w3.org/TR/access-control/). Is there any way to change the http://ajax.googleapis.com CDN so that it will set this header and allow cross-origin access to jQuery and other ajax libraries?

Not sending CORS headers also now means any script error details sent to window.onerror will be scrubbed and contain no useful information.
