3D occupancy map Roadmap

What is the roadmap for 3D octomaps? Based on this post 3D octomap generation they might be introduced in the future.

Neverthless in the doc of the occupancy_map extension (Occupancy Extension [omni.isaac.occupancy_map] — isaac_sim 2022.2.1-beta.29 documentation) there is a method “generate3d()” that I am not sure what it does.
