NPC raiding groups?

Seeing as how hostile human survivors are kind of a staple of zombie survival fiction, is there any plan or option on the table in the forseeable future for NPC survivor groups / gangs spawning occasionally that try to rob or attack the PC? (Or already implemented without my knowledge - beyond the Refugee center quest). Perhaps with the potential option of being diplomatically dealt with, lied to, or intimidated away through social abilities? Maybe even a local human gang headquarters could spawn rarely, that put hostile (maybe even cannibalistic) human scavengers out into the wilderness like some of the other monster-spawning locations?

Yes, micro-factions , dynamic groups of NPCs etc are planned, and I want them too, so if nobody else starts work on them, Ill probably add some form of them onto my todo-list.
