KGlobalAccel takes first shortcut in list as primary and other as
secondary shortcut, and KShortcutsDialog only allows to edit primary
shortcut, see bug https://bugs.kde.org/show_bug.cgi?id=341942
This result in problem where only Screensaver key is configurable and
Alt+Ctrl+L can not be removed. Someone will less likely use Screensaver
key for other purposes.

When the look and feel lockscreen theme failed to load for whatever reason,
it is supposed to fall back to a built-in theme to not lock the user out of the system.
The fallback did not work, however, and made the greeter crash with an invalid package
access, trapping you in an endless kscreenlocker_greet reboot loop.

Logging out from the locked screen is impossible. Logging out means
interaction with the session due to the session manager. The session
manager asks all applications to quit and applications are allowed to
ask for example saving changes. The session manager stopps the
logout in this case and asks the window manager to focus this window
and the session manager will only continue the logout once the
application resolved the situation. At any time in this process the
user is still able to abort the logout!
Switching to the application which needs interaction is impossible,
though as the screen is still locked. The result is a seemingly
frozen system as the logout cannot continue and there is no indication
what is going on.
Of course the lock screen cannot unlock the session for the logout as
that would circumvent the security. If the lock screen would unlock
one would just have to click the button and abort the logout really
fast to have the system unlocked. So this is clearly not an option.
The result is: we cannot implement this functionality in a working
and secure manner, so it's better to remove it.
