Using native absolute modules specifiers relative to the package root instead of double dots, transpilers or bundlers

I am payed for the task completion, not for the hours I play. Unless you are a consultant, you are in the same situation. To complete the task, such as migration of something to something else, I need to create an auxiliary Node.js-based command-line tool that is unlikely to be reused again. The tool should be flawless before its only use, but providing for potential future problems would be a pure waste of time. So I am always interested in the most straightforward solutions.

For some reasons, I really need to import a module saved in the project root into a module saved deep in the project folder tree. For example, let’s figure out the best way to import root.js into file3.js:

I could easily import a file from the package root into file3.js using a relative URL with several double dots:
