This seems to be a bug in the latest version 2.0.1. Rocks are no longer generating along the surface like they should (even reset my config) but instead are generating along the ocean floor lol.

Oh, and slight quality-of-life bug I guess, minecraft:grass_path should probably be added into the whitelist of always breakable blocks, since dirt and grass are already in there normally. Possibly mycelium and snow too? Also things like ice and glowstone that dont have a proper tool for breaking. Will ice spawn water or glowstone drop glowstone dust if they're not in the whitelist?
