Category icons still supposed to be app icons?

[palob]

Do we still need the icons applications-* in Circle/Square? Those icons are also present in the base theme, yet the app icons are prioritised. I know they used to show up in the menus of MATE/xfce/Cinnamon. The problem is they show up in spots where Circle/Square icons look out of place and where the icons fro Numix base could be a better solution.
