That was what I was actually referring to. ob-julia also requires two
Elisp packages: julia-mode and ESS
(https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-julia.html)

Now I see that you were referring to the actual Julia packages. Those
may be caught by Julia session code (org-babel-prep-session:julia) and
then a warning may be displayed.
