The argument does indeed exists. QtGui's primary function is to be a windowing system and graphics enabler. The minimum that is shared between QML and widgets.

QIcon is a style concept and belongs together with QStyle and we do not want QStyle in QtGui. As both the QFileSystemModel and QStandardItemModel relies on it, they cannot be moved to Gui. At least not without some surgery, and the surgery would imply source breakage so also not an option.
