What year Crosshairs do you have? I guess the rear brake braze-on is something they somewhat recently added as the Crosshairs frame I purchase this year has one.
Anyway, the hanger being loose is normal from what I've seen. When the brake lever is squeezed and the cable goes under tension, it will no longer be loose except for the side to side play (though it will likely gravitate to one side). The hanger has nothing to do with the brake alignment so as long as you get it set up correctly, the hanger shifting around won't cause any problems.
I attached a picture of my frame just in case you're curious.
