Villagers with more depth

As much as I love the trading system of the game, it would be wonderful if villagers had small reactions in certain situations. I know there are already a few, but more would be great (ex. When endermen spear, all nearby villagers will tilt their head down and avert their gaze, or after a raid, if there is an iron golem still alive in the villages, the villagers could approach them as a show of appreciation, like how baby villagers give poppies.),
