One thing missinh here is that dependencies are still published as ES5, sometimes with ESM as an addition. There is no easy way to provide a library with async/await as of today. We would need module:es2017 property in package.json for that. It mitigates a lot the benefit becausr in most code bases dependencies represent the majority of the final JS, and they gain nothing with this approach.
