This is just my opinions/ideas:

Guix System should target non-power users too.  It is already much
easier to install packages and services than in Debian, especially if
no sudo were ever needed as Arne wrote in his reply.

Perhaps if the unattended upgrades service were not included in
%desktop-services but selectable in the Guix System graphical
installer and selected by default, users would feel more in control
and existing users would not be surprised.

If unattended-upgrades-service-type checked with NetworkManager for
metered connections *and* if substitutes are available *and* the power
user can configure a blacklist/whitelist of trusted connections, the
only downside I see is less internet bandwidth during upgrades and
slightly more battery drain, but security is more important and the
more responsible default.

Maybe make it configurable if upgrades should be performed when on
battery.

Maybe users could stop an upgrade via libnotify notification?

A CVE notification service would be right for %desktop-services, I
think.
