Not many browsers support ES6 syntax, and in general, our engineers wouldn't prioritize support on our platform for something that would only benefit a small group of users or very specific use cases - that's likely why you haven't heard of an update after your report.

To make ES6 support something we want to work on, we'd have to know that this would really enhance the site experience for lots of users in a significant way. But most likely, it would only be used by a handful of particularly tech-savvy users for customizations that are cool, but not necessary to enjoy the site.
