Babel is ES6 to ES5 right? This seems to target a different audience. Namely moving your ES5 codebase to ES6 automatically.

Also I think the similarity in color scheme is very intentional. As this seems like a wink towards babel, being an anti-babel.

Yes, in fact it looks a lot like a preparing step towards babel: convert ES5 codebase to ES6, then use babel so it still runs on ES5 browsers.
