Why not updated es6/index.html?

Why you add breaking features to browser? Additional work for polyfills for detect and replace it. Only little part of standart library problems (from previous version, don't think they are fixed in current):

Reflect.ownKeys exist, but not works
Reflect.enumerate exist, but returns not iterable
all Reflect methods should throw error on primitive, but not in IETP
Math.asinh acuracy
Math.hypot accepts only 2 or 3 arguments
String.raw "lacks substituting" bug
Set#keys !== Set#values
String#startsWith & String#endsWith not throw error on regexp

Actually, I did some research, and the truth is somewhere in the middle. /./u in IETP will wrongly select the first of the surrogate pair, but /^.$/u will correctly select the entire character.

Is it possible to share the test input for which /./u is failing?
