Similar to fixDoubleRedirects.php but for broken redirects. While a pywikibot redirect.py script does exist, this script has the advantage of adding the jobs to the jobqueue, thus letting the wiki do it when it can.
So you're suggesting that, apart from using the jobqueue, the maintenance script would do the exaclty same thing(s) with broken redirects (not duoble redirects) that redirect.py currently does? Or would it handle redirects it cannot "fix" differently? (Just wanted to clarify the request — it's not like I can actually help write the script.)
