The way the USD exporter currently works, it is not possible to export invisible objects. As such, the 'Visible Objects Only' option was confusing. Exporting invisible objects means obtaining invisible evaluated objects from the depsgraph, which is not something that's currently implemented. Once that's done, we can reintroduce this option.
