Works best with Steep Surfaces, because of an existing (I view as) bug in Minecraft's code
Server-side at no cost of incompatiblity to the client
Performance friendly by utilizing Minecraft's surface generation, rather than it's more expensive feature generation
Supports mods that change the world using Minecraft's generation system (Terralith, Tectonic, Noisium, Biomes 'O Plenty, Geophilic, Lithopshere & a lot more)
