This is a quite philosophical queston if you look at it in general: "What value do you give a variable, that is not set?"
You are right, at first it seems strange to have a default of None. But how do you want to signal that no default is set yet? Especially if you think of a dict that can have multiple keys with each different values of different types?

Just out of curiosity: why dict.setdefault() has the default parameter that.... well, has a default value (None)? I used setdefault in the past, but I always specified a value. What's the use case of setting None by default?
