Native support for the Virtual Motion Capture (VMC) protocol.

Currently, VRChat tracking is largely tied to SteamVR or OSC.

Implementing VMC would allow users to pipe in bone and blendshape data from any VMC-compliant external software. This would bridge the gap between VRChat and the massive VTubing ecosystem, allowing for hardware-agnostic tracking on VR, Desktop, and Mobile.

And VMC output could be useful for using VRC to control something in a VTuber application or Blender/Unity/Unreal Engine

I doubt it'd be as useful but if possible it'd still be nice
