[Approved] Plasma 6 proposal: remove the ability to configure icon sizes systemwide in the icons KCM
Previously discussed at teams/vdg/issues#16 (closed), but I'm moving it here for more visibility, since this is the better place for it.
People use this setting as a way around using the global scaling slider to make things bigger or smaller, and it's the wrong way to do it. It only scales some icons in some apps, and the proportions of everything else look wrong. This is a general theme: we need to fix our own bugs, rather than offer user-configurability that lets people work around the bugs themselves, which generally causes even more bugs in the process.
This setting doesn't affect non-Qt apps, almost all of KDE's own QtQuick apps, and even random icons in QtWidgets apps. It's one of those "broken promise" features that needs to be universal to work, and because universality isn't feasible or even possible, it can't really work.
Let's remove it.
