Wife does intimate tasks for husband for endearment

A wife is obligated to do certain tasks for her husband for the sake of endearment. These tasks include pouring his cup, washing his face, hands and feet, making his bed, standing before him to attend to his wishes such as getting a drink and anoint him with oil.  There is a dispute as to whether these tasks are obligatory or optional. The Yerushalmi Kesubos (5:6) clearly holds they are obligatory for the wife to do them. Rashi (Kesubos 61a) and others hold that they are optional - simply advice that our Sages gave to increase the husbands liking of his wife. Simple question is what happened to these tasks. I have never seen a wife do these tasks for her husband. Even according to Rashi who says they are optional - but they are recommended in order to endear the wife to the husband. Furthermore if we say that according to the Rambam that when our Sages recommended something it becomes a command - then how can there be a dispute here whether these recommended tasks are obligatory?

Of greater importance why are these halachos not relevant. If this is a rabbinic decree as the Rambam and Shulchan Aruch seem to imply - then even if the reason for the decree are not relevant anymore - but the takanos are still active. In short you can't throw out halacha that way or ignore it. "kashrus is because of sanitation so it is not relevant" "Two day of Yom Tov because we didn't have accurate knowledge so it is not relevant today." "Divorce depending solely on husband's wishes is irrelevant to today" "Extra marital sex & incest is only for fear of having a baby whose father's identity is unknown or is a mamzer - not relvant today with birth control" "Mamzer is unfair and therefore not applicable today"  

There is really three issues here. 1) how could these obligations simply disappear? 2) They are reflective of and determine the nature of the relationship. If the values they reflect are Torah values then if we don't establish these values in the way described in Shulchan Aruch then how are they established? 3) If they are no longer considered Jewish values - what are the values in marriage and family relations?
======================================

Kesubos (61a): If she has four slaves - she may lounge in an easy chair. Rav Huna said that even though they said she can lounge in an easy chair but she fills his cup and makes his bed and washes his hands and feet. Furthermore Rav Huna said that all the work that a wife does for her husband she also does it when she is a niddah – except for filling his cup, making his bed and washing his hands and his feet and making his bed. Rava said this restriction for a wife who is a nida is only if she does the work in his presence but he is not there then there is no problem.

Rashi (Kesubos 61a): But she fills his cup and makes his bed – to spread the sheet something which is not strenuous – since it an act of endearment in order that she be more beloved to him. Therefore it is not comparable to the making of the bed mentioned in the Mishna which involves considerable physical effort and she can be forced to do it. She is not forced to do these works of endearment but the Sages merely suggested them as good advice as to how Jewish wives should behave. Except for pouring his cup -  when she is a Nida then all activities which draw them closer and increase endearment are to be avoided because they can lead to prohibited sexual activity.

Yerushalmi Kesubos (5:6): Rav Huna said that even if he had 100 maidservants to do the housework, his wife would still be forced to do the intimate tasks for him. What are these intimate tasks that she must do? It is to anoint his body with oil, wash his feet, and pour his cup. Why should she be obligated to do these when they have so many servants? Is it because it is inappropriate for a maidservant to do these tasks for him or because she has to do them? The difference between these two views is if he has male slaves rather than maid servants then it would remove the concern that maid servants should do these tasks for him and if she still had to do them that would show that the reason is because it is a wife’s obligation to do these tasks...It seems more likely that in fact she must do them solely because it is her obligation to her husband. 

Rambam(Hilchos Ishus 21:3-4): 3) A husband who takes an oath to prohibit his wife not to do any work at all – is required to divorce her and give her the kesuba. That is because idleness causes immorality. Similarly every wife needs to wash her husbands face, hands, and feet as well as pour his cup and make his bed and to stand before him to serve him. Examples of her service are to give him water or a utensil or take things from him etc.,  However she does not stand and serve his father or his son. 4) These tasks need to be done by the wife herself – even if she has many servants – she alone is required to do them.
  

Shulchan Aruch (E.H. 80:4-5): 4) And similarly every woman is to wash her husband’s face, hands and feet and pour his cup and to make his bed. (Some say that she is obligated to make all the beds in the house). And she is to stand before him and serve him doing tasks such as giving him water or a utensil or taking things from him etc. However she does not stand and serve his his father or son (However some say that is only when she is not dependent for support from her husband). 5) These works need to be done by the wife herself – even if she has many servants – she alone is required to do them. (There is a dispute regarding making beds see E.H. 80:8).
