remove-feature-flag

To remove a feature flag, delete it from Cargo.toml feature lists, remove the corresponding FeatureFlag enum variant, eliminate conditional compilation blocks and runtime checks, then run a full build and tests to confirm no regressions.

Removing a stabilized feature flag involves cleaning up Cargo.toml default features, stripping the FeatureFlag enum variant, deleting conditional compilation and runtime check branches, and verifying the project builds and tests pass.

You should retire a feature flag once it has been fully rolled out and stabilized, meaning it is no longer configurable and keeping it would complicate the codebase and future maintenance.

Clean up dead code branches by eliminating runtime checks, keybindings, and conditional compilation blocks that reference the removed flag, then validate by running the full build and test suite to ensure no remaining references.

Yes, removing a feature flag requires running the full build and test suite to validate that eliminating the flag from configuration, code paths, and runtime checks introduces no regressions or remaining references.
