You're right, the new signature is not used anywhere yet. Though 
I'm working on a patch to embed home profiles in disk images 
produced with `guix system image`. That's where this method comes 
handy, see example usage:

(image
(inherit efi-disk-image)
(operating-system (operating-system-with-provenance (load 
"./system.scm")))
(inputs
 `(("guix-home"
    ,(home-environment-with-provenance (load "./home.scm")))))
(partition-table-type 'gpt)
(volatile-root? #false))
