> What will happen in Wayland case? Nothing at all. Very few modern applications use server side font rendering anyway, the ones that don't either are obeying fontconfig rules independently already or will keep ignoring them. It's not even different for Windows and Mac OS X, some programs do their own font rendering that's different from the one provided by the system.
