Getting ARMeshClassification information

The ARMeshGeometry documentation references ARMeshClassification, but I cannot find any obvious way to get classification information for the mesh data.

I found the classificationOf(faceWithIndex: index) function in the Xcode sample project Visualizing and Interacting with a Reconstructed Scene, but it seems pretty complex.

Is there something simpler that I am missing?

It also seems from the code that a mesh doesn't have a classification, but only individual geometry faces in the mesh have a classification.

Is it common for a single mesh to represent many different objects (e.g., a chair, floor, and wall) all at the same time?

Thanks,
