Thank you @guimard! The change suggestion seems resolved and part of #369, but we still use an old version of commander, but I want to cut a release dropping support for node 10 and bumping commander to a modern version that no longer supports node 10.

This is described about commander 8.x.y

The current version of Commander is fully supported on Long Term Support versions of node, and requires at least node v12.

Version 9.x.y clarifies and sais node v12.20.0+ is required.
