@mnabid, @not-chicken:

In my testing of setting up GNOME 3.32 in a VM, `adwaita-icon-theme` was a soft dependency in practice. That package is currently a dependency of `gnome`, which means it doesn't get pulled in when doing a minimal GNOME installation, and although `gnome-session` 'worked', it wasn't usable due to the lack of icons. Hence the [current instructions in the Handbook for setting up GNOME](https://docs.voidlinux.org/config/graphical-session/gnome.html).

It seems to me that `gnome-themes-extra` is probably the correct dep here, though whether it should be a dependency of `gdm` or `gnome-session`, i can't say.
