Unless we have a definite plan that no ES.Next impl will support 
__proto__, then by all means don't standardize it. However, seeming the 
conclusion before was that not all use-cases of __proto__ are handled 
currently, once they are addressed in ES.Next, there will still be some 
transitional phase. I'd rather specify it in ES.Next, even if we do then 
agree to drop it in ES.(Next+1).

That said about any transitional phase, if it turns out we can make it 
[[Writable: false]] in ES.Next, then all the better (thereby only 
providing a transitional phase for those who can already use
