Adding new features to an existing Windows control, particularly one that has existed since the dawn of time, is a much bigger deal than adding to a simple utility. The last time that happened they added a whole new control, the Rich Edit.
You just add a new mode to the control that enables the new behaviour. Existing programs using it would work fine.
