Ancient Debris Mineshafts, or Lore additions

So when I go mining for ancient debris, it ends up creating this effect of a cave like structure, or a fantastical looking mineshaft. Maybe their could be a nether version of a mineshaft, that's also generated like a bridge through explosions. Cause man it always looks scarier and ominous, and Cool. If structures like this were to be added, something you could stumble across, it might get you a few pieces of ancient debris, and maybe a break from explosions and repetitions.

I think this is also an opportunity for LORE, which I think is super duper cool. I think with stuff like this we might want to have.... I don't know.... 

Nether excavation sites, to expand upon the coolness behind..... what this is debris from. Bits of redstone? the hint of a machine. A metal room. Hints of overworld.... a lightning rod, some copper. 

I just know that I want more LORE, from this ancient debris. Also if there was Ancient debris inside of a buried structure. this means you don't have to expand the ore size. in order to make it easier to find, cause a small bit might be attached to one of these structures.
