Mining Outposts(Cave Villages)

I think that since we got this large and expansive caves with new ores and other great cave related things, that we should see about villages inside these large caverns. Instead of the standard looking villages, maybe they could be mining posts with new miner villagers. Maybe these outposts could have more then just one iron golem as well and could have mineshafts that have miners working, pushing minecarts around and standing by ore deposits. It could even have that these mines slowly branch into abandoned mineshafts to keep those still abundant. I would also make this mining posts not as common as a standard village.
