My feeling, and I think the feeling of others at the meeting when we discussed traits, was that traits.js is a very nice library but that it doesn't offer enough to the language to warrant standardization, at least yet. The fact that there would be performance benefits to built-in implementations of traits isn't enough to make the case. IMO, libraries should generally be very widely used and very stable before they are added to the ES standard library.
