I liked the group feats you got in Storm of Zehir (NWN2), feats for the whole party that improved group accuracy, saves, etc in some situations. Some of them you got depending on your decisions in the adventure and some need specific skills or feats from your party members.
In Pathfinder (tabletop and Videogame) you have team feats, but not a common background. I really like to see this in BG3 but that does not exist in FR D&D.
I do not think the group background is related to this, and I agree with @NobodySpecial asessment. I would be cool to have some but I do not expect to see them ingame. Maybe if Eberron becomes a popular setting (LOL) and they made a DLC...
