Thanks for the help. I now updated the function `org-mw-item` to:

    (defun org-mw-item (item contents info)
      "Transcode ITEM element into Mediawiki format.
    CONTENTS is the item contents.  INFO is a plist used as
    a communication channel."
      (let* ((type (org-element-property :type (org-export-get-parent item)))
             (bullet (if (eq type 'ordered) ?# ?*))
             (the-item (org-trim contents))
             (level (- (/
                     (length (org-element-map (org-element-lineage
item) 'plain-list
                              #'identity info)) 2) 3)))
          (org-element-put-property item :post-blank 0)
          (format "%s %s" (make-string level bullet) the-item))))

With this change the following org input:
* A section
Here is a list of things

- An item
- Another item
    - A subitem
    - Another subitem
- Back to first

Is output as:
= A section =
Here is a list of things

* An item
* Another item

** A subitem
** Another subitem
* Back to first


This is close to the required result though there is still a redundant
empty line before "A subitem". How can  I get rid of it?

I also have no idea why I had to do the expression $level/2-3$ to get
the correct number of asterisks.

Another complication that I am currently ignoring is how to nest <UL>
and <OL> lists. But that's ok for now.

Thanks again!
