It seems common sense that the section would only apply to code in Wikimedia production, just like the +2 policy, but the text doesn't actually say so. Could that be clarified? We don't want to force people to go through Phabricator privilege requests for repos under labs/tools (Toolforge), for example.
Topic on Talk:Gerrit/Privilege policy
On Gerrit/Privilege_policy#Requesting_Gerrit_privileges it says that "To request membership in another group, create a new task under the Gerrit-Privilege-Requests project in Phabricator", "If there is a consensus of trusted developers on the Phabricator task, any of the Gerrit administrators can resolve the request" and "Gerrit administrators should not grant repository ownership to ordinary developers". Labs/Cloud is not part of Gerrit/Privilege_policy#Expedited_process_for_trusted_organisations and in light of Topic:Uswroi0fiud9on8o as well, it looks to me that (common sense or lack thereof) all access requests shall go through a Phab task.
