Confused about chunks

[JohnTheCoolingFan]

I looked a bit more into upstream code and now I'm a bit confused about what is planned for chunks. I've seen something in discussion #174 (links now pointing to nonexistent file/branch/commit), but it doesn't seem like that's the idea in current development. I've also seen some chunk position helper methods in helpers module, which uses UVec2 as a chunk index for some reason, which confuses me because chunks are often used to make a map around the center of the world as well. I've noticed that this helper is currently used unternally in rendering, but this is beyond my understanding currently.

What's the current plan for chunking?
