It should not, the parent `__init__` will be used instead.

The `Key` class, which `RaetKey` inherits from, is assigning the `opts` attribute to the class, even inherited ones.
The extra setup, which is different in each of the classes was moved to the `_prepare()` method.

This way, common class setup happens in `__init__`, and different setup happens in `_prepare()`.

I will try this once again to what actually got broken because, honestly, this change does not strike me as that problematic.
