If you enable Ceres fragment, will it replace something important? What if there is no tundra asteroid?

So I want to play in relica but maybe use some frosty stuff. The thing is, if I enable it seems that it replaces an existing asteroid between Moo, Tundra, Marshy or Water Asteroid and that concerns me if it will pretty much stop some content from generating. I haven't visited any planetoids besides the teleporter one, so I wonder if it will either stop you grom getting graphite, gassy moos, the experiment 52B or even the temporal tear POI, so what's up?

I think the new demolior can drop isosap and i think you can get graphite from the space pois but whats up with tundra biome?
