While not necessarily GNOME-specific, I'd still say icon packs
primarily target a GNOME or KDE audience, with Guix traditionally
shipping more of the GNOME-adjacent ones.  The name "newaita" also
sounds much like Adwaita, which as we all know is the default icon
theme for GNOME.

We currently have the following icon themes:

Would you suggest collecting them all in a single file?  Can that even
be done (particularly the mate one looks sus in terms of dependencies)?
