NPCs keep the outfit even after uninstalling SPID or mods that distributed those outfits.

Oh damn, THAT was the problem with SPID 7.2RC1? I'm okay with that. I'm not one to uninstall things and not expect problems. According to tonight's test results that's the version that successfully distributes outfits that get equipped (unlike the previous version) and doesn't crash (unlike the newer RC builds.) It's no longer available on nexus but you can find it on github.
