Underground abandoned houses

Add abandoned houses in caves that could connect two different caves, or maybe indicate that a spawner or something is nearby, while also providing loot for the player that is useful for caving and staying in caves at any level of progression as food, valuables, torches etc. They could also be in close range to other houses creating an underground village with zombie villagers that could maybe have a mining profession that only stays on them while they are underground. These villagers could also have useful mining trades such as torches, coal, obsidian or maybe exchange raw metals into ingots. These houses should be in an abandoned but still restorable shape, so the player could rebuild on them and create smaller bases through the giant cave systems in the new update.
