Do you mean "need not be" rather than "must not be"? "Must not be" means they shouldn't ever be. Most of my Jupyter notebooks are just code, but I've got some with long Latex mathematical derivations of formulas that appear in the code. I would actually like to be able to have that kind of thing in comments within the code itself. I don't do literate programming really though.
