Sorry for my late comment. While I think it's fine to publish LCWD Selectors API as it is, it would be nice if it can address my comment in [1]. By "address", I mean either define the desired behavior or explicitly mark it as undefined (which I think is better than not saying anything because an explicit "undefined" tells a spec reader that relevant discussions can be found in the list).
