The acl*repository-admins group grants rights for creating new Diffusion repositories, editing most existing Diffusion repositories, and via a PhabricatorHeraldApplication ACL creation of global Herald rules.
As T191182: Migrate active repositories in Phabricator Differential to GitLab has progressed, we are nearing or possibly past the point of wanting to allow creation of non-mirror Diffusion repos. There will certainly still be a desire for @StrikerBot and other bots/humans to be able to create mirrors of externally hosted git repos, but this will not require as many folks to have rights.
- Audit the users in acl*repository-admins
- Determine if acl*discovery-repository-admins is still useful
- Determine if Diffusion-Repository-Administrators still needs global Herald rule privledges
