This may be necessary even if the full overloading algorithm from the spec is implemented, as there are legacy interfaces that are ambiguous overloads in WebIDL, e.g.:

./html/canvas/CanvasRenderingContext2D.idl:
 void setStrokeColor(DOMString color, float alpha)
 void setStrokeColor(float grayLevel, float alpha)

./html/canvas/CanvasRenderingContext2D.idl:
 void setFillColor(DOMString color, float alpha)
 void setFillColor(float grayLevel, float alpha)

./html/canvas/CanvasRenderingContext2D.idl:
 void setShadow(float width, float height, float blur, DOMString color, float alpha)
 void setShadow(float width, float height, float blur, float grayLevel, float alpha)

... and possibly:
 ./xml/XMLHttpRequest.idl: void send(...)

Otherwise, it looks like all the overloads in WebCore IDLs involving DOMString can be disambiguated based on earlier arguments, or are intentional to work around this issue.
