Yeah. How exactly the extensibility hook is going to work is not
completely figured out yet. I suspect it'll take a while before this
whole thing moves to JavaScript.

It seems alright for now. Although I would encourage you to refer to
the built-in MediaStream.prototype.clone() method, so that if the
developer overrides it, you don't use that. (Alternatively define an
abstract clone operation and define clone() in terms of that. That's
what I usually do as it's somewhat clearer.)
