Maybe I should have clarified, it's not personal taste or
neatness but that you rely on an implementation detail of
xfce4-notifyd which rather simple and always displays a simple
notification window until it is closed, cancels or times out.
This breaks if xfce4-notifyd gains features like KDE's or GNOME's
notification daemons or if the user uses a different (there are
desktop-independent implementations) or no notification daemon at
all. notification daemons may hide notifications by default, keep
them around in a window until they are explicitly acknowledged or
deleted by a user or log them. This is what makes it a poor
choice for help messages.
