I agree that there's a ton of value in only using a subset of JavaScript, but wouldn't this be better implemented as a set of lint rules? Are there other advantages to a custom runtime that I'm missing? Even if it's only a subset of the language, the Python runtime probably isn't faster than Node.js.
