I suppose you could head-canon it that Sara did try, just behind the scenes: raising it with Carrisford, who then points out the issues with it, and Sara sees reason, and together they come up with the compromise. But then the fact remains this is still left out because putting it in would require explicitly examining the irrevocable injustice of the class structures and the author isn't really interested in doing that (and/because/so) doing this would undermine the 'little princess' theme.
