The thing is I'm finding trouble to dedicate to Ransack lately, so I can't really commit to any date.

Sorry you’re surprised. Issues are filed at about a rate of 1 per day against GLib. Merge requests at a rate of about 1 per 2 days. Each issue or merge request takes a minimum of about 30 minutes (across at least 2 people) to analyse, put together a fix, test it, review it, fix it, review it and merge it. I’d estimate the average is closer to 3 hours than 30 minutes. Even at the fastest rate, it would take 3 working months to clear the backlog of ~1000 issues. I get a small proportion of my working time to spend on GLib (not full time).
