In fact those files are there so in the future we could ease compatibility. GNUstep is not a Cocoa clone even though it tries to be compatible where it makes sense. It has some useful extensions. You may notice that the headers you find in GNUstepGUI are not part of AppKit on Cocoa. Some of them should be considered private to GNUstep (they are needed for integration of the display backends or Gorm.) others are true extenstions. When the need arises and someone is willing to do the work, you may be able to build a GNUstepGUI library or framework on top of Cocoa. It would only contains the gui extensions of GNUstep but otherwise relies on AppKit. This would make it easier for GNUstep based apps that use the extensions to run on Cocoa.

This has already been done for gnustep-base (ie. GNUstepBase) but it will take some work to cleanly do it for gnustep-gui.
