Section 9, reads:

  If the Program does not specify a version number of this License, you
  may choose any version ever published by the Free Software Foundation.

In this case, we use ‘gpl2+’ as the license.

The general convention is to stick to the upstream name:

  https://guix.gnu.org/manual/en/html_node/Package-Naming.html

Regarding the union package, perhaps we can actually leave it up to
users to install both breeze-assets and breeze-icons if they want?
After all, since these are separate packages upstream, we don’t have to
provide a union of both.  WDYT?

Could you change the URL to a mirror://kde URL?
<https://github.com/archlinux/svntogit-packages/blob/packages/breeze/trunk/PKGBUILD>
shows that the official tarballs can be obtained from kde.org.

With these last changes, we should be all set!

Thanks,
Ludo’.
