Very true. What could be done is to add a member method like this:

bool KNotification::supportActions() const

This method would check whether the knotify plugins associated with this 
notification support actions. knotify would then do something like this:

for plugin in pluginSelectedForThisNotification:
     if plugin.supportActions():
         return True
return False

In the current implementation, all plugins would return False in 
supportActions(), except NotifyByPopup which would return True if the 
current popup server supports actions.

Would it make sense to implement this?
