### Cleaning up the feature flag

<!-- The checklist here is to help stakeholders keep track of the feature flag status -->
- [ ] Create a merge request to remove `<feature-flag-name>` feature flag. Ask for review and merge it.
    - [ ] Remove all references to the feature flag from the codebase.
    - [ ] Remove the YAML definitions for the feature from the repository.
    - [ ] Create [a changelog entry](https://docs.gitlab.com/ee/development/feature_flags/#changelog).
- [ ] Ensure that the cleanup MR has been deployed to both production and canary.
      If the merge request was deployed before [the code cutoff](https://about.gitlab.com/handbook/engineering/releases/#self-managed-releases-1),
      the feature can be officially announced in a release blog post.
    - [ ] `/chatops run auto_deploy status <merge-commit-of-cleanup-mr>`
- [ ] Close [the feature issue](ISSUE LINK) to indicate the feature will be released in the current milestone.
- [ ] If not already done, clean up the feature flag from all environments by running these chatops command in `#production` channel:
    - [ ] `/chatops run feature delete <feature-flag-name> --dev`
    - [ ] `/chatops run feature delete <feature-flag-name> --staging`
    - [ ] `/chatops run feature delete <feature-flag-name>`
- [ ] Close this rollout issue.
