This is what Country Nation had to say

After she came up empty handed in the nominations grab, the addition of Shania has to surprise some. Not that the CMA would ask her to perform -- but that she would accept. It's called class.

I only agree with this to a point. It was class when she performed after the Woman in Me snub. It was class when she performed after not getting anything for Come on Over. Now, it's just silly. "Class" is lost on the CMA voters. They have none of their own.
