I vaguely remember having discussed this issue a little, we found
that yes; many apps do use the "root" argument but that it was not
fundamental to the way gtkbuilder works (i.e. people can simply store
widgets/objects in separate files). I suppose this functionality could
be added to the builder in the future by adding a "rootnode" property
to the builder if its really needed.
For your particular use case though, you dont need to instantiate
a useless window; there's no need for toplevel ui objects to be
GTK_TYPE_WINDOW().
