Looks awesome. I'll certainly be putting this to some use :)
That said.

While I personally agree with this opinion, isn't it typically the case that a frontend dev's workflow already heavily relies on Node? It's probably already installed for all that Wangular.js nonsense, so it being tacked on to one of the heavier CSS preprocessors probably doesn't make much of a difference, no?
Yes, you're right that most frontend developers already rely on Node for various tasks.
This would be most helpful for those who still haven't introduced Node as a dependency and trying hard to get away without it :)
In any case, as I mentioned in another comment, the fact that one can write a minimal preprocessor in ~30 LOC could be useful to start a conversation about the current state of the art regarding frontend development.
