Why is cooking and cleaning not the duty of the wife?

After reading Muṣannaf Ibn Abi Shaybah, 29677, we get to know that the Prophet Muhammad PBUH gave his daughter, Hazrat Fatima (RA) the duty of managing the affairs of the household while he gave his son-in-law, Hazrat Ali (RA) the duty of managing affairs outside the house. Why then, according to majority of scholars, cooking and cleaning is not the duty of the wife? I know that the Hanafis say that it depends on which class the woman belongs to but I am trying to understand the opinion of the majority. I got to know about the opinions of the schools of thought by an answer here:- https://islamqa.org/hanafi/daruliftaa/7935/ They have said > You mention regarding the cooking of food. Firstly, a wife is not legally even required to cook for her husband. This is the case in the three schools of Fiqh and one of the two opinions in the Hanafi Madhhab. Now, if the husband comes and asks the wife to cook a certain type of food for him, then the wife is not legally obliged, but the rewards for doing so are great.
