Bismillah
This is the whole point behind narrating such hadeeth and making Umm Salim a role model Jennifer is that the vast majority of women would just behave under emotional distress. But this woman (and the point is not giving food and pleasure), but the point is how to bring such news, how to analyse it, she introduced it as that Allah Took back the trust He originally granted. It is about how a Muslim woman should perceive the most difficult test a partent can go thru.
BTW, my grandmother behaved in a smiliar situation almost the same. Her daughter was very ill, she was looking after her and my granfather was downstairs, the daugter passed away, my granny came down saying she slept. Only in the morning that she broke the news, however, also after she felt the daughter passed away, she said 3 times Alhamdulelah for loosing my daughter. There are even role models in the modern time.
So to sum it up, no the hadeeth is not about giving the husband food and pleasure, it is about how to perceive/behave during tests and trials.
Leave alone that it also indicates how Allah Rewards those who are patient and accept Allah's decree.
