I've been a Gerrit administrator since Chad made me one back in 2015, and have used it to mostly single handled manage the repository ownership requests process. Due to recent events, my administrator status was removed under the assumption that those rights weren't needed, but that turns out not to be the case. Furthermore, https://www.mediawiki.org/wiki/Gerrit/Privilege_policy makes it clear that one needs to be a Gerrit administrator to enact the types of changes I used to in the past.
 Per T218761, but I can't even see the audit log to verify that anymore.
 Specifically, I can no longer edit membership in the mediawiki group, which is (correctly) owned by Administrators.
