The Bug
A recent change that made strongholds not generate below lava level has caused them to spawn above the surface more commonly than it used to. According to the calculations, the deepest part now goes to Y 16 instead of Y 4, causing strongholds to spawn higher. People speed running might use advantage of those exposed strongholds.
How to Reproduce
Use the seed 326795066205547 with Default world type
Teleport to -64 76 1673
Look around the area, noticing several exposed parts and weird world generation
The Error
The stronghold spawned excessively high above the surface. It is a lot more common to find one of those strongholds in your world.

It’s similar, but not a duplicate. If you notice the lowest height a stronghold can generate has been changed in 1.17 compared to 1.16, it doesn’t go down to lava level anymore. This caused the stronghold in 1.17 to generate way higher than 1.16.
Since this ticket relates to MC-199948 instead of duplicates it, I can confirm that this is an issue.
