If you're using KDE, you aren't likely to end up using Adwaita as your icon theme. The primary users affected seem to be users of the GNOME and XFCE flavors of Fedora where it's the default theme.
That's probably libadwaita (the successor to libhandy), which by the way also forces the Adwaita GTK theme. This post is about the Adwaita _icon_ theme. Those are 3 different components (solib, CSS, icons) that all happen to be called Adwaita.
