Believe it or not, there's a few people who have a little morale. But a good purpose for publishing graal rules is so that players can't argue that they shouldn't have been banned. It would would also serve as Graal Polices' guidelines of what deserves a ban or not. Some GPs ban for reasons (sometimes ridiculous reasons) that a different GP would not ban for. (for example different GPs say different things about certain tower blocking situations)
