It's true I do not have a lot of examples where this is a hard need.

The only one I can think of is the Powerdevil notification which appears 
when it is about to hibernate your computer in 10 seconds because you 
are running out of battery. This notification has an action to cancel 
the auto hibernation. If actions were not supported, Powerdevil could 
decide to use a dialog box instead (in fact I think this notification 
should always be presented through a dialog box)
