@koshic please review.

I appreciate your help and it would be really awesome if your name appeared in the contributors list at the main github page. If you wanted to copy these changes or use another approach in a different PR you make, I would merge your PR instead.

Whatever you want to do, either way thank you

Thank you! But this is unnecessary. Open source for me is about collaboration, not badges / achievements / co-authoring in titles )

I'm interested to make other changes needed to remove dependencies for yarn PnP but will be busy until tomorrow maybe. Thanks for the valuable input and discussion.

Ok, and I can check new version of esmock in my setup if you publish it today.
