I just had a lengthy discussion about it with my GSoC student and we came up with the \
following plan:

* for 4.8 use a hack to fall back to the legacy implementation if a screen saver is \
                configured
* advertise the new functionality in the release announcement including that you \
don't get the new super-awesome  lock screen if you use an old screensaver and that \
                the old screensavers are not secure
* advertise a new improved screen saver functionality in 4.9 based on QML with GHNS \
                integration and more
* announce that the old screen saver support will be removed in 4.9 in favor for the \
new support and because it's an  old X dependency which we need to remove in order to \
start the transition to Wayland

This gives us no pressure to implement everything now for 4.8 and we don't have \
unhappy users. In best case we  already have the new QML screen saver support in 4.8 \
and can get the community to port their screen savers to  QML. Also we give a good \
technical reason why we have to drop the screensavers.

I hope that makes everyone happy :-) (and is also the easiest way for me in 4.8 as I \
don't want to spend too much  time on screen savers).

Cheers
Martin
