The reason that I use this is because putting all of the different functions in one function (OnDialogResponse) is programmatically incorrect, and to better be used by someone like me, where each feature in my game mode is in it's own include file.

If you look at a script with many dialogs, OnDialogResponse is the ugliest thing.

EDIT:
It's useful to me, I just though someone else might appreciate it. If you don't find it useful, don't use it.
