In cases when you do "stringifier attribute", sure.  It saves you the 
trouble of having:

   attribute DOMString foo;
   DOMString toString();

and prose that says that invoking toString() does the same thing as the 
foo getter.  Which is not very much trouble, imo, compared to what a 
typical toJSON prose description would need to do.
