95% of the language features were supported during my funding period. Since then, it's nearly reached 100% feature parity, and the tooling/interfaces have been much improved. The code is a lot cleaner, a lot smaller, more modular, more extensible, and uses standard IRs.
I will say I very much like Redux and have used it for dumping AST nodes. I recently became interested in a project where I wanted to hack on and extend the grammar. I found this difficult in Redux, Coco (and friends), and couldn't use CoffeeScript because of lack of source map support previously.
I think a huge benefit for Redux will be making the grammar very clean and extensible. I know it's on your roadmap to CS-ify it.
Edit: Oh, and if you're curious, I wanted to play around w/ translating the CS AST to TypeScript AST, but I'd obviously need to add more typing/declaration syntax to the grammar.

If you want to try it out, see the online editor here: http://michaelficarra.github.com/CoffeeScriptRedux/ (shameless plug: it was built using my new browser bundler with full minified-JS to CoffeeScipt source map support: https://github.com/michaelficarra/commonjs-everywhere)
