I found a bunch of small things, and I've offered a few suggestions.

This command should fail, because the origin repo's main branch should be protected against direct pushes -- modifying main (and stable branches) really should require a PR.

That's totally right, I am proceeding step-by-step and at the moment the main is not protected yet as this is still in development mode. Planning to follow your approach in the near future.

The only difference is that this git push origin main will be replaced by creating a new branch and then "create a pull request with those changes"
