Not that it's really an issue here because Coffescript is basically Javascript anyway, but legible source is important even for developers who don't end up reading it.

The people who actually read the code are a small subset of the group that depends on being able to read the code if necessary. I haven't needed to dive into the source for everything I've integrated into a product because of inadequate API documentation or bugs, but it happens, and it's not something you can generally tell ahead of time.
