Do you need commonjs output format?

Do you need commonjs output format? In v-f-d 2.x, we compile output into both esm and commonjs format. I have a idea about abandoning commonjs format. Give me some advices.

We often still compile to commonjs. If you make a branch with a version of what you're considering, we could test it for you
