Since in CCL, as I have just read in a post by dode, the competition is just inside races and not really between races, would it not make sense to have a filter on the leaderboard that displays only the ranking for a certain race. I know it can be done with goblinspy, but wouldn't it also be nice to have in-game?
Such filters are already implemented in other statistics pages (like I can query my history/statistics against certain races), so I don't see why it shouldn't be possible for the leaderboard. What you normally use the leaderboard for is to check what your team's placement on it is and what statistics the top teams have. If only the relation between teams of the same race is interesting, it's very tedious to find out what rank inside your race you have.
