Scroll lock thoughts

Hi, I wonder why after every update of KDE Plasma is “scroll lock” button unable to activate and I have to make manual adjustments in settings files to activate this function.

To rephrase my question - Why developers thinks that this key / function is better to be “dead”.

I use it in Windows on MS Excel pretty often. Also I wonder why is “scroll lock” do nothing in Libre Office Calc… Or do you anyone knows how to enable same funkcionality as in Excel?
