You lose the ability to have

Since NestedClass is an enum member, you should use
Colors.RED.NestedClass.value() or just Colors.NestedClass.value() for
calling its value.
If you don't want it be a member, just don't initialize it in the enum body.
class Color(Enum):
RED = 1
class NestedClass:
pass
Color.RED.NestedClass = NestedClass
Now Color.RED.NestedClass() can return something useful.
