Just to clarify - we do have support for node_modules/ resolution (with all of its quirks and gotchas), otherwise we wouldn't be able to load npm packages. However we made a hard stance that CommonJS is only supported in npm dependencies and cannot be used in user code (ie. you must use ESM in your application code).

Until you try to build a TS project that imports an .mjs from node_modules that doesn't work right. Oh, set the project to type=module, nope, then other crap breaks. I mean, you can get it all working, but simple and easy are two words I would not use for modern node, especially when working with typescript.
