Then we'll be a lot further ahead than if Valve had never paid for this work to be done. I don't know what better alternative you're after. Isn't this open source work? There's no ongoing dependency. If Valve shut up shop tomorrow we're in a better state than if they'd never funded development, aren't we?

Absolutely. That's why I'm glad Valve did this, and also why I wish it wasn't necessary.
