I previous mentioned looking at hiding the ratings when they don't apply to the league/division. For our league, I've set it up so that when we have the calculator set to "none", then the ratings information and player skill_level information is not shown/shared.
This diff on github covers it off, but if you're going to use it, you may want to double-check my code -- I wasn't able to test all of the changes (they're all marked with "// XXX: Rating"):
