This is what I was wondering as well. Especially since Webpack's tree-shaking doesn't _really_ work for a lot of third party libraries: https://github.com/webpack/webpack/issues/1750 https://github.com/webpack/webpack/issues/1750 I imagine Rollup might do a bit better on that front since its the bundler that popularized tree-shaking in the first place. Can anyone with experience with Rollup comment on this?
