Still very common among non-professional track riders in Japan, home court advantage I guess. I like square taper. It lasts forever. Modern solutions are far more fragile. I've been using the same BB for over 10 years now, and it's not quitting anytime soon.
Edit: Carleton is right, non-square taper BB's are probably stiffer. But how strong are you? Can you flex one of these? I sure can't.
