That's not correct. Keith Packard and other people rejected the idea of adding a new XCMS layer in the X server. He said color conversion belongs into the window manager. So we are using today the X property system to communicate between applications, compositors and configuration libraries/systemsettings dialogs (beside the Xinerama/XRandR gamma table APIs). IMO the main difference to wayland is that: we do not know a similar inherent transport mechanism for meta data like Xatom is for X11. (I share Graemes position, that the meta data communication path should match that of wayland in order to remain compatible. I do not like the idea to randomly add different mechanism as wayland extents capabilities. Most relevant image file formats had adopted some way to attach meta data. Otherwise workflows are not flexible enough.) That meta data communication path has __not__ necessarily the need to configure wayland.
