Another option I would like to see is the outright deletion of some of the very specific and abandoned mags.
Looking at abandoned list link supplied by @ernest (cheers for that and for all the work you have put in) there are ~4,000 abandoned mags.
While many are in need of new mods, there are a lot that just need to be deleted. They can be recreated in the future if they need is there but I doubt a lot will be claimed.
Maybe in a couple of months that could be looked into.
