This wouldn’t be possible, at least not this easily, because the trick
requires the config file name, and that means it’d typically need to be
a macro used within the config file, like:
(define (%config-file-service file)
(simple-service 'config-file
etc-service-type
`(("config.scm" ,file))))
(define-syntax-rule (config-file-service)
(%config-file-service
(local-file (assoc-ref (current-source-location)
'filename))))

I’m a bit reluctant to make it part of ‘%base-services’ (if it were
technically possible) because that may deceive users, since it takes
more than this config file to reproduce a GuixSD config.
