Does not support standard ActiveSupport cache methods like cleanup, mute, and silence!, which may break workflows relying on these features for maintenance or logging.

Explicitly maintained for Rails versions prior to 5.2 with no new features added, making it a legacy choice that lacks updates for modern Rails ecosystems.

Serializers must be added in a specific order and frozen to avoid runtime errors, adding setup overhead and potential for misconfiguration in dynamic environments.

Enabling TTL refresh on reads adds write operations to all cache hits, introducing latency overhead that may negate performance benefits for frequently accessed keys.
