I'm not sure if there's even an existing maintenance script that will do what I want. It looks like refreshLinks.php doesn't update the iwlinks table, except to remove entries from deleted pages. Further, the documentation for purgeList.php doesn't indicate that links are updated. Would running pywikibot touch.py genuinely be the best option here?

Btw, looks like "page_links_updated" (which I didn't realize existed) is the correct field to look at, not "page_touched". However, that wasn't added until MW 1.23.

Lack of an obvious route forward; seems it will require at least some code changes

Then these code changes should be outlined or discussed in this task (or dedicated subtasks should be created).
I don't see what makes this stalled by definition...

Ok so someone needs to make a task, sure. It is discussed in the comments at least

Marking it stalled at least means on the Wikimedia Interwiki workboard it’s not read to go
