Is defining get/set methods for every field overkill?

Obligatory note that boilerplate 
https://code.dlang.org/packages/boilerplate exists for just this 
reason:

     class Label : Renderable {
         @ConstRead
         private const string text_;

         @ConstRead
         private const TextAlignment textAlignment_;

         @ConstRead
         private const Color color_;

         this(Dimensions dimensions, string text, TextAlignment 
textAlignment, Color color) {
             this.dimensions_ = dimensions;
             this(text, textAlignment, color);
         }

         override Cell[] render() const {
             Cell[] cells;

             for (int x = 0; x < 0 + text.length; ++x) {
                 cells ~= Cell(Coordinates(x, 0), text[x], color);
             }

             return cells;
         }

         mixin(GenerateFieldAccessors);
         mixin(GenerateThis);
     }
