Progress delayed is progress denied. If you want a better web platform, that means wanting one that is different than the one we have today. It is also the case that standards committees are not outfitted with effective fitness functions (the ability to predict market success, e.g.). The best we can do is to iterate and be data-driven. I do not know what "correctly" means in this context, and I submit that you don't either. What we _are_ doing is making the progress we can with the best available data we can gather (polyfilling via Polymer, building large-scale apps, observing existing libraries and their challenges, etc.). It's fine to critique the method, but bring data.

If you have specific concerns regarding their utility or design of these specs, I'm hopeful they can be aired as we continue to iterate. Shipping is not the end; it's a new beginning.
