cave villages

In the new update with "cheese caves", there could be a new type of village. The houses could be indented into the side of the cave wall and made out of different stones. The villagers would give you ores if you trade with them. There would also be small mining shafts. They would also have iron golems that would protect the villagers from hostile mobs found in caves. I think that these would be a great addition to the caves and make them more exciting to explore.
