Game Suggestion: Cadavers should spread disease

RIght now there is little to no reason to build graveyards in game. They are hilariously expensive and only give a small happiness bonus to the few villagers who go there to mourn. There are always better things to spend expensive stone on than a huge building that gives almost no benefit.

My suggestion: Cadavers should spread plague and rats if unburied. The same should be true with the raider corpses, who all magically disappear shortly after being slain. That would force the player to choose between graveyard sizes in game, whether to invest in a good one or to get a small one built just to bury a few bodies. It would also become a priority quickly as deaths mount.

I wouldn't even mind a corpse pit to throw the raiders into. It would be nice to be able to collect loot off slain raiders, like a few swords and halberds that weren't shattered in the fight
