It's because LLMs will soon start building real-world objects via CAD. This is the first step. Look at things like the Adam plugin for Onshape. Works great with Opus. It built a toy car for me with one prompt.
There already are LLM plugins for Blenders and prompt integration for model generation, rigging and co.
If the idea is to support Blender for use with “Digital Twins” or “World Models” then the first step is to start with accurate geometry. Anything less is slop.
