Official information on `arguments` in ES6 Arrow functions?

by

Chrome, FF, and node seem to be wrong here, Babel is correct:

Arrow functions do not have an own arguments binding in their scope; no arguments object is created when calling them.

looking for official docs here

Arrow function expressions evaluate to functions that have their [[ThisMode]] set to lexical, and when such are called the declaration instantiation does not create an arguments object. There is even a specifc note (18 a) stating that “Arrow functions never have an arguments objects.“.
