Safely removing feature flags after a full rollout involves identifying the scope, verifying safety, removing flag checks, and inlining the winning code path. This process also includes deleting legacy files, updating tests, and updating the flag registry.

The best way to clean up legacy code from rolled out features is using a pattern-guided workflow that follows established patterns to ensure safe, auditable changes. This process includes deleting legacy classes, removing flag checks, inlining the winning path, and updating tests.

Feature flag cleanup handles tests by updating them to reflect the winning code path and deleting legacy tests. It also runs validation steps and quality checks to confirm nothing is broken and maintains a clean history.

Yes, you can automate flag removal across multiple services. This cleanup workflow applies to software projects with feature flags across services where the flag is fully rolled out and the legacy path must be removed safely.

You should not use an automated workflow for flag removal when the feature flag is not fully rolled out to all users. This process is strictly for when the legacy path is no longer needed and the winning path is enabled for everyone.

A shell ceremony workflow for legacy code cleanup is a structured process that uses established patterns to ensure safe, auditable changes. It guides you through scope identification, verification, flag removal, path inlining, and registry updates.
