And with es6 shim, Map/Set SHOULD works on IE5, and all modules depend on Map/Set (but not depend on complex features such as Proxy) also works. So that's what I mean migration step by step. Some of your codes migrate to ES6 API, but keep working on legacy browsers. It's very important for real products. Or migration is totally impossible until 2023 if all pre-ES6 browsers disappear it that time.
