I reckon that Visual Studio has virtual solution folders because it has 
this one-level hierarchy "solution -> projects".
Qbs has the same limitation ATM. Wouldn't your issue be solved by adding 
the possibility to nest projects?

Project {
     name: "foo"
     SubProject {                // basically a fancy references entry
         name: "libs"
         displayName: "My Libraries"     // not sure if this is needed
         filePath: "src/libs/libs.qbs"
     }
}

where src/libs/libs.qbs contains a Project item with all the libs which 
can be even built stand-alone without the surrounding top-level project.

This looks quite similar to your approach and we need something like 
this for Qt anyways (oh and actually for the qbs submodule in Qt Creator 
as well).

If you're going the folder road, I'd say use a dummy root folder.
