If you really want it you can open and issue and try to be convincing...but I'm pretty set on moving forward with just ES modules. I attempted this in the past and compiling CommonJS to ES modules was pretty complicated at the time. I'm not sure it would be worth doing, but perhaps it would be. I want Zwitterion to be forward-facing

I can absolutely sympathise with wanting to avoid to avoid adding support for an outdated system that would be a headache to implement and (I assume) a significant maintenance burden.

But there are a lot of commonjs modules out there, and many/most of them will never migrate to ES modules. It's such a significant downside compared to Parcel that I'm honestly not even inclined to try zwitterion out, let alone get involved with the project by making detailed feature requests.
