Feature Request - 3D overlay apps

I know that XR_EXTX_overlay is a provisional extension. It looks like it’s the successor to OpenVR’s VROverlay functionality.

I am very interested in injecting 3D objects in another app’s scene as an overlay app, rather than 2d textures. Is there a plan or existing request for this feature? If not, I’d love to hear whether I’m the only one dreaming about this.

I can only say that I am interested in this as well, and it seems like it would be widely interesting. You might consider having your company join Khronos to participate in internal discussions if you want to advocate for features like this and become a part of the decisions made here.
