A lot of libraries are published along with various types of bundles and non-bundles, including usually the source, so the user can pick which one is best for them. For example, you can import just one Lodash module at a time so you don't have to bloat your app with the whole library. This seems like the best of both worlds We're converging on better norms for JS dialects/module systems, but we're not all the way there yet, so I don't see much purpose dropping support for multiple formats when some people might still need some of them If you do want to go clean-slate and drop all the ceremony at once, I recommend Deno :)
