The Bona fide relationship immigration qualification

After the revised travel ban which was upheld by the U.S. Supreme Court with the modification that the people of the six banned Muslim nations can come to the U.S. if they had certain “bona fide relationship” with someone or some entity close enough with which they have established a relationship. Included in it were also people who have obtained visas from employers in the U.S. plus student visa holders and other relationships. But it left the interpretation of the bona fide relationship to the government to define it. And the government defined it in the narrowest terms possible which included husbands, spouses, children, step children, fiancé, siblings but curiously excluded grandparents, sister and brother in laws, aunts and uncles and cousins to say the least. I do not understand how they came up with the definition of the bona fide relationship but now a federal judge in Hawaii has expanded the definition to include the excluded members of the family (already overturned by the Supreme court and the battle has raged on since). I don’t know who came up with this but to me grandparents are really more important than step children and fiancé who are not your blood relations and who have not established any relationship with their step parents and fiancés, while grandparents and aunts and uncles and cousins are blood relatives who are already there from day one. This is my definition of a bona fide relationship and I believe that everybody has their own definition of it and the Supreme Court should have defined it explicitly instead of leaving it to the interpretation of various people who are in charge of immigration policies.
