Sorry, I was unclear. I didn't mean to necessarily suggest TS as a candidate for Dart's goals. (Though there is STS...)

I meant to point out that you can't just assume a priori it was NIH syndrome, as Google's heavy adoption of TS is a counterexample.

Makes sense. Google is a very large and diverse place. (And sometimes a lot of unpleasant infighting and politicking around tech choices.)
