I am not sure what you mean here. Also, note that org-mode-tests has /local folder running local podman builds with reproducible environment.

I guess it could be fine. Though I am not sure how the images are going to be upgraded then as the required packages (Elisp and system) are updated to new versions. > All in all, I forked the project [1] but the SourceHuts build (CI) > requires some fee, right?

Yep. Or maybe even Emacs itself? I am not sure if Emacs is currently using CI.
