Yep, emacs org-mode (org-babel for code exec, etc) is such an awesome datascience platform, I wish more knew about it and used it. One primary issue I have sometimes though is the barrier to entry for others to use, as everyone has a favorite editor and only emacs really properly handles org files, but, I have also found that it's not that hard to put the notebooks in a ci pipeline that processes so people can just submit pr's independent of using emacs and still see the results. What they miss though is the interactive nature of org-babel.
