Unity3D's status/roadmap for supporting OpenXR?

I know that Unity Technologies is publically supporting the development of the OpenXR standard, but I am struggling to find any details about the level of support currently available in Unity3D for interfacing to an OpenXR runtime or the roadmap for introducing support to do it. Version 1 of OpenXR was released in July with two runtimes supporting it at launch (Microsoft's WMR and Collabora).

Is anyone able to provide any information about Unity's plans or point to any public posts/documentation?

 

It seems Unity forum posts are not very well indexed with Google. Searching on the forum I have found a bit more information. As of 31st July 2019 Unity employee mfuad replied to this thread that there is no clear release plans:

I guess any update on that would be great.
