That's according to document of the spec on FD.O.
IIRC, the so-called KDE support is a patch provided for mandriva which
is not widely-adopted.
Some names of config values are even prefixed with Gtk, so I don't
think other toolkits can
handle this natively without patches.
XFCE has a xsettings manager, too, but it can only affects the
xfce/gtk+ programs.

Believe me, those values can be properly set in gtkrc as well.

Those so-called non-gnome apps are almost all gtk+ apps and not the KDE ones.

If you set a gtkrc file properly, this can be achived, too.
Programs for other desktops don't obey that settings in
gnome-settings-daemon at all.

Personally I think we need a cross-desktop config system, too.
