Quest hand tracking OpenXR hand subsystem (XR Hands) support?

Do the com.unity.xr.oculus or the new com.meta.xr.* packages support Unity's OpenXR hand tracking subsystem for Quest hand tracking? Is there any sort of hand tracking provider given, or has that not been implemented yet? I haven't found mention of it in the documentation yet, but there's Meta Aim stuff in XR Hands so I assume it's at least planned.
