Possible breaking change
* The `ModelMutation` used to generate the default return value of the model as `snake_case`. So, the model `FooBar` would be set to `fooBar`. That still works the same for the endpoint, but in python it is weird to have to `return cls(fooBar=instance)`. This changes the default attribute to use `foo_bar` .
