In addition to using the bot to clean up stale issues, we are also using it for label hygiene and triage package automation.
- Label hygiene. Detect missed deliverable and track the version of regressions. See https://gitlab.com/gitlab-org/gitlab-ce/issues/49201 and https://gitlab.com/gitlab-org/gitlab-ce/issues/48518
- Triage package, we work remotely hence there is no bug grooming meeting, we do all of this in issues. A triage package is generated for each team by the bot every week. See https://gitlab.com/gitlab-org/gitlab-ce/issues/52781
You can set this up rather easily via the gitlab-triage project. The project is public https://gitlab.com/gitlab-org/gitlab-triage
