It's perfectly accessible.
var obj = { ["__proto__"]: 42, __proto__: null };
assert(obj.__proto__ === 42);
assert("__proto__" in obj);
assert(Reflect.get(obj, "__proto__") === 42); // ...if I remember R.get's
name/semantics
assert(Object.getOwnPropertyDescriptor(obj, "__proto__").value === 42);
assert(Object.getPrototypeOf(obj) === null);
And so on.
On the original topic, SpiderMonkey's implemented this since Firefox 35, which
I think means the current Firefox beta implements the __proto__ non-duplication
requirements.
