I think this is probably a good thing. France reimposed border controls when it held ceremonies to mark the 60th anniversary of D-Day in June, 2004. That same year, Portugal reintroduced checks during the European Football Championships. Finland did the same during the 2005 World Championships in Athletics, held in Helsinki last August.
