How well are USDZ features supported?

Texture tiling and skeletal animations in USDZ files are currently not supported in iOS 13 by QuickLook (in Xcode & Preview they work like a charm though).

Is this something that will be improved with the new iOS & ARKit?

Will we have better/propper validation scripts in the USDZ converter to know what features of the USD standard are beign supported?

Thanks
