I don't think it should. You can use operator.add() if you need to fall back to a __radd__ of the right operand.

operator.concat() is Python API to the sq_concat slot. It falls back to __add__() just because instances of user classes defining an __add__() method only have an nb_add slot, not an sq_concat slot.

Third-party classes (maybe NumPy arrays, I don't know) can have different implementations of sq_concat and nb_add.
