Why should it be changed? IIUC .guix-authorizations and (guix ...) care 
about the key that things were signed with, not necessarily the primary 
key, so it seems to me that it needs to report the subkey fingerprint, 
not the fingerprint of the primary key it belongs to, as the primary key 
is irrelevant to them IIUC.
