One reason is the relative nature of output; the viewing light  
determines the d-max, the d-min, and the densities... another is the  
extreme gamut of such papers and inks: do you want us to limit your  
blacks and whites to what a color checker black can manage? That can  
be done through press-proofing type emulation prints, but most  
photographers want the deepest blacks possible, and the whitest whites  
possible, not intentionally limited blacks and whites.

Iterative processes don't tend to work well for this. Thats not really  
the issue, it lies elsewhere, with expectations and processes.
