Did you seriously just plug your blog post in es-discuss?

Are you really explaining the open-closed principle and composition vs
inheritance to a mailing list of people interested in language design?

About why class is added:

ECMAScript would have looked different had it been designed from scratch
today - but given your criticism everything apart from mixins for classes
is impossible without breaking compatibility and mixins are being explored
separately anyway.
