For correctness, (push ...) and (goto-char ...) obviously need to be
located within the (let ...).

No, with a full parse tree, `org-element-contents' on a citation object
returns the list of all citation-reference objects within.

I don't know. In any case, they need to be treated as regular object
(e.g., they are expected to have a filter associated to them).

If some back-end doesn't need to export directly citation references, it
just needs to skip the relative translator.
