Happy to announce that your request has been partially considered and included as part of the v6.14 release. With this release, Admins can now add the Person section to the Shared 360 Layouts. Admins can perform this configuration from the Administration > Sharing > 360 Layouts > C360 Layouts page.
This feature is implemented in both SFDC & NXT versions.
Thanks for posting!
