XR_META_body_tracking_full_body Khronos Release?

I'm one of the Godot XR developers, and for licensing reasons we have to consume the OpenXR headers from the official Khronos release (https://github.com/KhronosGroup/OpenXR-SDK - Apache-2.0 Licensed).

I believe  XR_META_body_tracking_full_body is the only Meta extension that hasn't been published through the official Khronos headers. Is there any plan or schedule for publishing this one?
