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.

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'.
