VRInput Branch?

After trying to understand how EditorVR is abstracting VR input systems I discovered branches where work has been done on this:

https://github.com/Unity-Technologies/input-prototype/tree/new-vr-input

and

https://github.com/Unity-Technologies/input-prototype/tree/editorvr/main

Exciting, but I haven't been able to get it working. Standard non-vr input (ex: mouse) works fine, but VR input fails silently which makes debugging difficult.

Is there something I'm missing?

 

This was a cross-post and was already answered, so I'll post a link here, too:
