Too many aquifers on biome surfaces at Y=63 and below

At the 63y and below, aquifers tend to generate more frequently, ruining some flat, warm biomes, such as badlands and deserts, where water actually cannot be generated (that's why lake ponds have been removed in the new generation. on these biomes).

Also, having all caves always flooded could be annoying for some players who prefer to explore caves without having to climb hills, where caves tend to be drier.
