I went ahead and installed a small number of mods and then they crashed they're working without issues so far, however I noticed this new World Type option added by one of them upon creating a new world.
Upon clicking the Customization button that comes with it, these are the only UI elements greeting me on the screen.
The UI here confuses me to no end. I've got no idea what this is supposed to do, or, for that matter, which mod added this in the first place.
What mod has the ScaryGen world type option, and how do I use it?
Update:
uhm. Looks like I enabled it by accident with the default values.
Now I'm even more confused.

That would probably be Additional Buildcraft Objects
I can't find any documentation referencing it, but the repository for the mod references it, as well as the forum post. It seems to be a bit of a hidden feature.
I have no idea what the index option does, but the *Level things seem to be the height to generate it at. geostrataGen is for supporting a mod called GeoStrata.
The input field is what to replace the water with, can be any block as far as I can tell.
