I think I remember. No warning then. We've still got a few instances of  
methods (in ActionsTool) using it but I'm torn between replacing them with  
the utility lookup plus fallback or leaving them as they are for 2.3 and  
changing them without fallback later. The current code provides an elegant  
lookup with fallback.

Okay.
