I really like the way the ES6 spec is coming together. Generally the way in which abstract ops are used and internal methods are specified is much clearer and more uniform in ES6 than in ES5. Also, the table of contents is much better structured. I like your classification according to indexed collections, keyed collections, control abstraction objects, reflection, etc. These editorial issues are not always fully appreciated, but +1 to them.
