I think it makes sense. Currently, org-babel-edit-prep:R/julia always start the session when editing src blocks with a valid session header, and other backends don't. It would allow users to change the behavior. > 2. Check the new variable and attempt to run > `org-babel-<lang>-associate-session' in org-src-mode definition. I think associating the edit buffer with some session doesn't require starting the session, which is at least feasible for ob-python. When editing python src block, users can use C-c C-p to start the session themselves for evaluating code. So it would be nice to allow a value of 'associate in the customization, which means just running `org-babel-<lang>-associate-session'.
