We have to design software which suits the majority of our users. On a mailing 
list like kde-core-devel I had hoped to not get answers like "I like this 
feature". You are also a developer and I am sure that you have considered in 
the past to remove a feature which other people liked, but you had to remove 
it for various reasons.

But as said as long as you are on X you can always just run xscreensavers to 
get your animations. You can also start VLC in fullscreen mode or write a 
small wrapper for the new to be written QML based animations in the screen

even there we should have our defaults to protect the environment by turning 
off the screen and keeping the CPU in the lowest level. As well we should not 
give the users the wrong feeling that they need a screen "saver" to save their 
screen. Whatever we will call the new animations in the screen locker it will 
not be a "saver".
