I use -O and sometimes it even makes a difference to performance. I know that people using embedded Python sometimes like to use not just -O but -OO to remove docstrings because every byte matters. "No one uses -O" is, I'm afraid, one of those myths popular among Python users, like "No one uses anything but CPython" and "Everyone uses an IDE". I feel your pain -- I used to work with an otherwise really good Python coder who was strict about following every best practice in the book *except* he insisted on using assert for all his error checking.
