I'm using Terralith alongside Ore Tweaker and realized that I was getting almost no vanilla oregen in my world.

While I did manage to resolve this by manually adding all the various Terralith biomes to the respective "OVERWORLD" whitelists of each file (and updating the "MOUNTAIN" and badlands ones to their specific values) it was a lengthy process and resulted in extremely large lists.

If biomes were instead filtered by tags, such as #minecraft:is_overworld this would not only allow for much shorter lists of modded biomes, but would also greatly increase "out of the box" support for other modded worldgen (provided it was tagged correctly).

For those who stumble across this:
Here is the list of a ton of biome ids that others can copy paste into their oretweaker whitelists.
