For example, if I:
1. edit `server.properties` to
`share.coordinator.state.topic.replication.factor=3`
2. run up the broker as per the quickstart:
```
KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"
bin/kafka-storage.sh format --standalone -t $KAFKA_CLUSTER_ID -c
config/server.properties
bin/kafka-server-start.sh config/server.properties
```
3. `bin/kafka-features.sh --bootstrap-server localhost:9092 upgrade
--feature share.version=1`
4. `bin/kafka-topics.sh --create --topic my_topic --bootstrap-server
localhost:9092`
5. `bin/kafka-console-share-consumer.sh --bootstrap-server localhost:9092
--topic quickstart-events`
Now I will see logs in the server like:
```
[2025-08-12 16:28:56,007] INFO Sent auto-creation request for
Set(__share_group_state) to the active controller.

reached because only 1 broker(s) are registered.
