I see no problem with this contribution, but unrelated, it does make me realize the lack of CI/CD.

Since commit 22eaaa79cfda added a LICENSE to facilitate contribution and distribution, I am legally obliged to ask the following:
Do you license these changes under the project's license (BSD 3 clause as readable in LICENSE in the latest master commit at the time of writing, which is 22eaaa79cfda) ?
