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
