@antfu made some changes - noticed that new behaviour also triggers for ESM, which is incorrect

Also added usecase, where default is not an object - Node finds named exports, but returnes them as undefined (because tries to access it on default): https://stackblitz.com/edit/node-kyzwfi?file=cjs.js,index.js

Also removed ability to put all instance properties on exports:

// class-cjs.js
class SomeClass {
  variable = 1
}
module.exports = new SomeClas() 

// test.js
import * as cjs from './class-cjs.js'
expect(cjs).not.toHaveProperty('variable')
