This ended up implemented in WebKit as Location.ancestorOrigins(), a 
method that returns a static DOMStringList with the origins of the 
ancestor browsing contexts in reverse order (top-level browsing context 
last, parent browsing context first). It doesn't respect sandboxing.

Are other browser vendors interested in implementing this?
