Default [Q] What is the "no lockscreen" task for?

Hey guys,
a long time ago I noticed a task called "no lockscreen" or "Keine Bildschirmsperre" in german which takes 10 MB Ram, so I asked myself why
it takes 10 MB Ram to have no lockscreen. I might understand it wrong and 10 mb more or less are not that much but I was wondering whether I could disable it.
