Disappointing, but hardly tragic. It would have been tragic if the standard
adopted a definition of concepts that failed to improve support for generic
programming or made it worse worse. I think Doug Gregor - somewhere in the
http://cpp-next.com/archive/2009/08/what-happened-in-frankfurt/ - summarizes
the problem nicely.
