Title: Use shim blob with importScripts to use CORS for Worker

I suggest this to overcome problems with cross origin loading of the Workers. Bypassing your CDN for this kind of stuff is simply not desirable.

importScripts unlike Worker constructors do support CORS, which makes no sense whatsoever.
