This is a little ridiculous. Andhra, Mysore and Kerala are all part of South aka Dravida. Rahul Dravids father named him Dravid because he wanted to stress the fact that he was a very proud south Indian. Dravida is a Sanskrit word that came to mean all that is south of Vindya's. Himachal would obviously be a reference to all regions adjoining the mountains. Rajasthan is only between Sindh and Punjab - big deal! Why do you assume all regions have to be named explicitly? I don't like the National Anthem because it doesn't mention my home town Coimbatore or village ? Do you see how silly it gets? Tagore has traced the cultural boundries and regions of the sub-continent. It has nothing to do with political set-ups like princely states or British fiefdoms.
