kafka-topics.sh required arguments and defaults

Step 3 of the quickstart suggests that partitions and replication-factor are optional kafka.apache.org/quickstart. Also, the options list provided by bin/kafka-topics.sh explicitly mentions that " If not supplied for create, defaults to the cluster default." (kafka_2.13-3.0.0)

bin/kafka-topics.sh --create --topic quickstart-events --bootstrap-server localhost:9092
Missing required argument "[partitions]"

...
--partitions <Integer: # of partitions> The number of partitions for the topic
being created or altered (WARNING:
If partitions are increased for a
topic that has a key, the partition
logic or ordering of the messages
will be affected). If not supplied
for create, defaults to the cluster
default.

...
--replication-factor <Integer: The replication factor for each
replication factor> partition in the topic being
created. If not supplied, defaults
to the cluster default.
