Overhauled Dungeon Generation (Mob Spawners)

Many people including myself would probably like a better experience in dungeons when traversing the brand new caves. I mean think about it, we have a whole new underground generation, as of 21w07a we have slightly improved looking mineshafts. The dungeons are such a nice find and I think it should be overhauled

I think that the following should be added or changed

• More to explore (make them a lot larger)
• More dangerous
• Rarer at the cost of more valuables
• Varies depending on different biomes and depth (dungeons that generate in the grimstone levels have ancient variants as they have been pressed down for centuries, dungeons that generate with stone have stone variants, more modern versions
