Little World Tweaks

Patches of diorite, granite and dirt are adjusted so most caves are removed, while andesite and tuff patches appear more often. Dripstone caves now pair granite with coarse dirt and plain dirt patches, and lush caves pair diorite with calcite. Pointed dripstone spikes are more common, trees grow taller on average, fancy oak trees appear more often, and jungle bushes are less common.

The changes are delivered as a data pack that alters the worldgen data for biomes, so the effect applies to worlds generated after installation and not to chunks that already exist. It is described as compatible with most mods that modify biomes and with other worldgen data packs. Only the server needs the mod to change generation; a client may install it too, but it is optional there. The code is under the MIT License, and the project is not open source. Files exist on Fabric, Forge, NeoForge and Quilt, with the Data pack option for servers.
