* intricate syntax (and customisation!).
*
* It might be even possible to retrieve everything in a single call:
* ```
* return get_users(
* array(
* 'role__in' => 'administrator',
* 'capability__in' => 'administrator',
* 'fields' => 'user_email',
* 'count_total' => false // no need to count them; improves performance.
* )
* );
* ```
*
* Alternatively, the function `admin_emails()` may simply be marked as deprecated and
* `get_users()` used instead. This requires debugging! (gwyneth 20230919)
