> Not to mention that ECMA is working toward ADDING new feature to the language instead of deprecating some obscure ones, which would make the language easier to use. We'll see what happens longer-term. Certainly until recently the focus has been on the web (and deprecating features on the web is rather pointless: the web still supports things that were deprecated two decades ago, as dropping support breaks sites which makes users change browser or stick with an older version). There's plenty of things listed in Appendix B of the spec, "Additional ECMAScript Features for Web Browsers", which contains much of the worst parts. Perhaps more will move there in the future, or to some separate section of previously-standardised-but-now-optional features.
