This is version 0.1. That's the "prove it can be done, and get it to work" stage of development. The extra features beyond the basic glue come later. In the case of react-three-fiber, which is the React alternative to this, the library does things like setting up sane defaults for you (things like color management, shadows, a camera, etc). Those weren't there in v0.1. The extra bits take a little more time.
