Put a stop to dungeon excavation, sofort!
I know how this hype to uncover every single dungeon found and dig away the ceiling to expose it to the sunlight came to be, but I think this is getting out of hand, when dungeons as deep as halfway to bedrock layers getting this treatment. Is this necessary?
You might say you're wanting to preserve the landscape, but you do realize by destroying the overhead cover of the dungeons you're actually ironically destroying the landscape above it?
Just please, stop this madness. I'm getting sick of seeing deep shafts on the ground with a spawner underneath. Things as deep as that would be preserved better by NOT uncovering it.
