I have noticed on a recent commit [1] that the "document" property of 
the window object is now defined as [[Unforgeable]] (and still 
readonly). As per WebIDL, it makes the property non-configurable (in 
ECMAScript 5 terms). Consequently, it will make impossible to wrap the 
object document with an ES.next proxy [2] and replace the "document" 
property value with the wrapped document.

I think that there is definitely a use case here as replacing the 
document with a proxy could help developers fixing the DOM and adding 
workarounds to browser bugs. Consequently, I think the "document" 
property of the window object should be kept configurable.
