For maintainers, that's fine, as the information is already exposed. Re: [1], that's an historical artifact of the way former Planet maintainers tried to map feeds with LDAP UIDs. It's been ages since that was introduced and I honestly don't recall why it was originally needed and whether that field is effectively still in use :-)
