How long would you expect to keep both around?

Currently half the platform results directories are Chromium, comprising a third of the LayoutTests/platform directory and a quarter of all of LayoutTests. These results directories also tend to change far more frequently than others. I am worried about the long-term impact of adding even more Chromium results, since svn update times are already very high and typically spend a large proportion of their time updating Chromium expectations. Do you have an estimate of the impact on checkout times?
