Very good point. Maybe this helper class could help expose more complex 
models to QML as a list model, by providing a sub-selection of the data. 
Something like:

============
ItemModel {
     id: itemModel
     model: myModel
     column: 4
}

ListView {
     model: itemModel
}
============

where "myModel" could be a tabular QAbstractItemModel, and in 
"itemModel" we select the 4th column in order to create a list model. 
Though whether it's useful, it's another matter. :-)
