and what has protecting the screen against burn-ins to do with security? 
Nothing, right.

Btw. we are not the only ones who go the way of removing screen savers in 
favor of lock screens. The same happened at GNOME and at Microsoft. So somehow 
the people working on such features came all independently to the same 

Yes sure there are still CRTs around, there are Plasma screens around and 
somewhen in the future OLEDs might be used which show the problem. Does that 
mean that we should use a default (because that's what it's all about) which 
is not optimal for the 99.9 % of our user base that actually uses LCD screens?

and again that is orthogonal. There is nothing preventing anyone to add an 
animation to the lock screen.

the implementation has been kept there AFAIK because people complain that we 
wanted to remove it. It would be nice if the people who want to have the old 
screen savers would step up to support the maintenance. Yes it would have been 
easier to just remove it and would have removed lots of complexitiy. As I 
wrote it's a HACK and has always been like that.

But the discussion again shows that just removing it completely and tell 
people to use XSS if they want screen savers would have been the right choice.
