Are you planning to remove this value from WebSettings, etc, as well?

Yes. In http://trac.webkit.org/changeset/146351 this method was made a stub, to
avoid blocking the WebKit roll. In the new patch I removed this line. As long as
this patch lands after the rolling WK past 146351, there will be no change in
default behavior on the chromium trunk. Once this patch lands, I will go back in
WK to remove the stub (and roll chromium DEPS if necessary).

 
   // Disable antialiasing for 2d canvas if requested on the command line.
   settings->setAntialiased2dCanvasEnabled(!antialiased_2d_canvas_disabled);
