Watching https://github.com/nodejs/TSC/issues/1445, looks like CommonJS packages in Node.js will need to add a `"type": "commonjs"` to their package.json to have compatibility with this new flag (and possible future compatibility if/when Node swaps to ESM by default without the flag).

 @365a528d @544fb7bb so this does not affect files inside node_modules, so it won't break every npm package everywhere?
