This is only partly true as Seth pointed out on this list just recently
(not sure which topic it was though): IIRC short name wins only applies
if both packages provide *exactly* the same thing, and this shouldn't be
the case here.

There *are* packages explicitly requiring notification-daemon, so this
needs to be rephrased: Why is xfce4-notifyd choosen *although* (!=
"unless") some packages are hardcoding notification-daemon, which
already satisfies all requirements?
