Let's face it, when most people come across a village in survival, they loot the blacksmith and check for trades. This doesn't seem like enough. It no longer feels "exciting" to come across a village. I think that they should implement new types of villages and more buildings in villages with new uses. For example, a type of village that spawns in extreme hills biomes and has awesome bridges that spawn with it, connecting it with other buildings on separate mountains. This would be more for the decorative side of things, but new village buildings that have new uses would be not only more exciting, but helpful to avid survival players. What if one type of village building had a tutorial station where you could walk up to it and a villager would teach you how to craft an item (for a price). This would be useful if you had a house near the village, and needed to craft an item. Instead of exiting out of minecraft to get onto the wiki, you could learn how to craft the item IN minecraft.
Another type of village could be in a castle that's guarded by villagers with armour and swords.
I feel like this suggestion would add to the more lively side of minecraft.
