I think we should always check the existence of this function.
However I also wanted to propose to reject any change of the GW mode if we do
not have these APIs implemented. But tihs can be done with a later patch.

Dunno...this was a just a copy/paste from other "print" APIs. Maybe we just
remove the "optional" text from here for now.
