What would left to do to make this lister work? It seems already in good state, and it would be useful to index gforge.inria.fr since it will be closed soon (https://gforge.inria.fr/forum/forum.php?forum_id=11543). For the gforge.inria.fr case specifically, it is worth noticing that project creation is closed already, so a one-shot listing could be an option if it is lighter to set up: I wrote a small script to do that, but after a few requests to https://archive.softwareheritage.org/save/, requests are throttled. I would be happy to send you a listing of the public projects hosted on gforge.inria.fr if it could help.
