Gary, you are still miss the point of this proposal. Please see my comments
in review. We are not forcing things out of tree, we are thinning them. The
text you quoted in the review makes that clear. We will look at further
decomposing ML2 post Kilo, but we have to be realistic with what we can
accomplish during Kilo.

Find me on IRC Monday morning and we can discuss further if you still have
questions and concerns.
