Use MappingPolicy, when youre 100% sure, that youre okay with the exact same reaction every time to a certain intent.

I only use it for things like unhappy path in forms.

(In a FormAction) Bot: What is your ID? User: I dont want to answer that Bot: Do you want to stop the form? Buttons Yes/No

Now its very clear, if the user hits the ‘Yes’-button (‘Yes’ is just the title of the button here, the payload is another intent) I send a special intent, which should always lead to a ‘Deactivate’-Event (one that stops the FormAction). This can be easily achieved if the MappingPolicy triggering the Deactivate-Action.

Other things I might think of are FAQ-Bots, but even there Id rather have may bot ask if somethings wrong if the user repeats a question multiple times.
