Yes. Everyone agrees .contains is good. It will happen. There was some debate about .has vs. .contains, but from what I recall I was one of the only people pushing for .has, and I have since changed my mind. I am hopeful in fact that .contains is so simple and uncontroversial that we can push it through the post-ES6 spec process very quickly, including into implementations.
