B.3.1,  “The __proto__ pseudo property” will eventually be moved out of the annex, right?

If I may: I have two questions about this section.

1. Quote: “Manipulations of this property as tracked by the Boolean valued primordial internal variable UnderscoreProtoEnabled.”
    What is a primordial internal variable? That term does not appear anywhere else in the spec.

2. Quote: “The default initial value of UnderscoreProtoEnabled is true only if this property is initially present on the primordial Object prototype object.”
    I would have guessed that the variable being true also depends on whether or not Object.prototype is in the prototype chain.
