Hi Brian,
 
They do affect the producibility levels.  They also affect reliability  and 
that's one of the major factors of the different classes.

I am a  little confused by tables 9-3 & 9-4.  The headers of the columns  
calls out as Class 1,2,3. Why are the minimum blind/buried via hole sizes  
referenced to the performance classification? Shouldn't they reference  
producibility  levels A,B,C?
