Early Access: New Design Formats in Cesium ion

This is great news for Rhino users!
I work in Rhino Technical Support at AppliCraft, the official Rhinoceros distributor in Japan, and I’ve been exploring workflows connecting Rhino, GIS, and Cesium. So far, I’ve been using a georeferenced KMZ-based workflow, so I’m particularly interested in the Early Access support for Rhino (.3dm).
I recently shared some of my current experiments here:
Rhino Models in Cesium — General

Do you have any plans or an approximate timeline for making Rhino (.3dm) an officially supported format in Cesium ion?
