Sounds reasonable. I like "inline-mode", although no strong opinion.

Do people have reasons to use older versions even when they could use
the newest?

For example, python2/3 or MathJax4,4- were breaking and some people were
relying on legacy code. So, we had to provide some extra versions checks
and toggles on Org side as well.

Correction: `org-sbe' will execute src block. So, my example is not
completely accurate. Getting src block body is still doable, but a tiny
bit more tricky:

#+begin_src emacs-lisp :prologue (org-babel-ref-resolve "test[]")
(+ 1 2)
#+end_src

It think that it will be logical to add reference resolution to
:prologue/:epilogue. I will see what I can do.
(I may need to look through which header args are resolved and which are
not - there seems to be no consistency)

(This will work because ob-org, by accident, produces body as result of
evaluation, with default header args)
