It should not be essential. What you demonstrated is two bugs in Org mode.

Fixed, on main.

`org-latex-link' assumes that it is safe to use
\ref{<org-latex--label ...>} in order to refer to an existing src block.
However, it is not true.
`org-latex-src-block--engraved', `org-latex-src-block--minted',
and `org-latex-src-block--listings' only produce a label when src block
has a caption.
We should generally not need to put a caption in order to refer to a
source block listing. At least, it does not look like we need it from

Thoughts? Ideas?
