Because I use a window manager (awesome) implementing its own

Sonata display a GTK window directly to build its notification.
Furthermore, the Sonata notification window shows a progress bar, which
is not possible with the notification standard. So there's no way it
uses it right now, and that would probably be a regression, but IMHO
it's worth it for better integration with all DE/WM.
And it can be just an option. ;)
