Just pushed live an app today that I had to cave and add babylon-polyfill so it would work in IE 11 after trying to polyfill a dozen missing es6 runtime features from various sources.
That made the final JS output 25% larger, a 90kb increase from the polyfill library alone, so here's a serious optimization waiting to happen (the natural dying of an older browser).
