Another BIG reason: It's impossible to export a whole hierarchy qualified.
I.e it would be neat if the user could write:
import Graphics.UI.Gtk
And then have Gtk re-export sub-modules qualified, so you could write
"Button.new", "Window.new" etc. etc. As it stands you have two options:
prefix all the "new" functions with the kind of widget they create
(buttonNew, windowNew), or force the user to add a gazillion qualified
imports.
The problem would be again that no one knows, where "Window" comes from. 
Better would be

import Graphics.UI.Gtk (Window, Button, )

Don't know if this extension would be worth the trouble.
