If you are using Jujutsu you can achieve a basic way to maintain a public repo from a private monorepo with very little code and without Copybara. I wrote up how to do it here: https://vihren.dev/blog/20260625-jj-public-private-workflow/

The main function of copybara is not moving code but modifying code to make it suitable for a different repository structure, build system, etc.
