Now that we no longer support IE we can raise the minimum ES target a bit. Changing to es2015 shaves off ~17% from the main bundle size, also it prevents generators from being transpiled into regular functions etc. so I would guess it has the potential to give some general performance improvements too. For fun I also tried to raise it to es2022, this gave a slightly bigger bundle than es2015 so I think es2015 could be an ok target unless we need something newer for some reason.
