I think when you only use desktop-services, it works.
For me it fails, I tried to adopt this to my
%desktop-services-sans-ntpd but I haven't found the right way to
make use of it:

(define %desktop-services-sans-ntpd
  ;; List of services typically useful for a "desktop" use case.
  (cons* (slim-service)
         (screen-locker-service slock)
         (screen-locker-service xlockmore "xlock")
         (avahi-service)
         (wicd-service)
         (udisks-service)
         (upower-service)
         (colord-service)
         (geoclue-service)
         (polkit-service)
         (elogind-service)
         (dbus-service)
         (guix-service-type config =>
                            (guix-configuration)
                            (inherit config)
                            (substitute-urls
                              (cons* "https://bayfront.guixsd.org";
                                      %default-substitute-urls))
                            (authorized-keys
                              (cons*
                               (plain-file
                                 "bayfront.guixsd.org.pub"
                                  (string-append
                                   "(public-key
                                    (ecc
                                     (curve Ed25519)
                                   "
                                   "(q
                                    #8D156F295D24B0D9A86FA5741A840FF2"
                                   "D24F60F7B6C4134814AD55625971B394#)))"))
                                 %default-authorized-guix-keys)))
                               %base-services))

Identation broken because this happens when you copy from emacs
with X into terminal emacs.

Obviously this fails because "config" is not known.
Just modifying the service the way you did it doesn't work for
me.
I'm open for ideas on how to erase ntp from the services in a
better way, I'm running a replacement for ntpd.

Later this %desktop-services-sans-ntpd gets used in (services).
