subuid/gid are _not_ unprivileged. They are an userspace feature by
the (privileged) setuid binary 'newuidmap', see
<https://manpages.debian.org/buster/uidmap/newuidmap.1.en.html>.
I don't think there's currently a mechanism for that in Guix System,
except manually creating and modifying /etc/subuid appropriately and
installing the setuid binaries. However, I suppose that the 'user-
account' record could be extended to support subuid/subgid and
automatically create /etc/subuid.
Greetings,
Maxime
