I've pushed this to version-1.3.0, along a slightly edited version of a
a diff Julien shared earlier that fixed an issue with building the doc
after recent changes.
Thank you both!
Closing.

The xz-compressed image is 23% smaller than the original ISO image (with
built-in zlib compression), but the extra decompression step is
unconventional and often a hindrance for users. See discussion at
<https://lists.gnu.org/archive/html/guix-devel/2021-04/msg00497.html>.
* Makefile.am (release): Do not compress ISO images.
* doc/guix.texi (USB Stick and DVD Installation): Remove ".xz" suffix
from URL and file name.
(Copying to a USB Stick, Burning on a DVD): Remove introductory words,
@enumerate, and first item.

Hi!
This takes the simple step of providing plain ISOs only (rather than
.iso + .iso.xz as some suggested).
One advantage is that, unless I’m mistaken, this can be done without
breaking string freeze.
We’ll also have to update <https://guix.gnu.org/en/download> on the
release day.
Thoughts?
