It's mostly a TC39 process, where they have to go through a very pain-staking process to ensure it breaks virtually nothing in real world code, one that takes several years. So far, the only language feature successfully removed is `arguments.caller`. There are a few others deprecated for future removal:
- `Function.prototype.caller` - `arguments.callee` - `RegExp.$1`, `RegExp.global`, and friends - Most everything banned from strict mode. - And likely others.
