Why was anybody pushing for this bill if that's already the case?
They likely shot it down because 'caste' carries a very different meaning in American parlance. It mostly relates to wealth and they absolutely DO want to discriminate on that basis.
If I had to bet though it was a security thing. They want caste named explicitly because a good deal of Indian immigrants are dealing with it despite it supposedly being illegal.
