Because to ship screensaver output over vnc takes a lot of CPU
and network resources. IMHO this should not happen by default,
because newly setup machine with a few users running vncserver
hammers the machine.
     If they want to setup screensavers explicitly, fine, but
at least you can lart them for that :-)
