Thematic mapping of point cloud attribute data

I am interested in thematically mapping attribute data from point cloud data in cesiumJS. When I interrogate (from within CesiumJS) attributes in the 3D-tileset (created using Cesium ION) I can only see the intensity and classification attributes, all other attribute date is not present. Is this a short coming of ION or CesiumJS?

This is something on our near term roadmap that I’d definitely love to see. There’s a feature request here for generally allowing the user to choose what per-feature properties to include:

Having some sample data from our users here would help push this feature forward. What other kind of attributes do you have that you’d like to include?
