And we could add a warning in grid_search.py:

if not getattr(clf, "scale_C", True):
warning.warning("scale_C=False is not recommended when using grid search: see http:// for a discussion")

If you would like the opinion of user (i.e. me) I think this is the best solution for intuitive use of the Lib. And having scale_C=False as default.
