Does a Muslim wife have to cook and clean for her husband?

In response to this question , Ustadha Shazia Ahmad quotes a Shafi'i jurist, > “45.1 (Abu Ishaq Shirazi:) A woman is not obliged to serve her husband > by baking, grinding flour, cooking, washing, or any other kind of > service, because the marriage contract entails, for her part, only > that she let him enjoy her sexually, and she is not obligated to do > other than that. Rather, it is considered sunna in our school for > the wife to do the housework...[al-Muhadhdhab fi Fiqh al-Imam > al-Shafi’i] However, U. Shazia Ahmad still goes on to say, > A woman is not obliged to work, but rather, she is expected to take > care of her husband, children, and home. This is from the sunnah in > our school, and it is considered obligatory in the Hanafi school. In > traditional societies, a woman is honored and admired for her > efficiency, cooking skills, and cleanliness in the home. You will find > that these womanly duties, when done well, contribute to the safety, > security, love, and emotional stability of a Muslim household. Do not > undermine them for they are important things that affect the whole > family. She also ends her answer with a link to another Q&A about the obligation of obeying husband in everything . So, this leaves me confused: According to Islam (the Shafi'i school, in particular) is it a woman's duty to cook and clean? If cooking and cleaning are not a woman's duty by default, would they become her duties if her husband requires her to do them? (given that obeying husband regarding permissible actions is obligatory)
