Yes, indeed.

OK, that works - I didn't know about the three-element list
form. Thanks!

Perhaps the docstring for org-latex-listings should include
the three-element list form, with a pointer to the
org-latex-packages-alist doc for more details.

There is also a (perhaps unlikely) scenario where this is not enough:
previewing typeset code where I *want* to use minted:

--8<---------------cut here---------------start------------->8---
* Code

\begin{minted}{c}
  printf("Hello world\n");
\end{minted}
--8<---------------cut here---------------end--------------->8---
