The name of consumer groups may be the same in different namespaces, so IMO it's necessary to keep the namespace.

The name of consumer groups may be the same in different namespaces, so IMO it's necessary to keep the namespace.

I don't think so. Firstly, namespace is a resource isolation to prevent topic or group names. For users, the topic or group without namespace is set in the client code, while adding namespace prefix to topic or group is handled in the program. The direct display of namespace prefix may cause confusion to the user. Secondly, other language clients such as Java remove the prefix of the above problems, which should be kept consistent.

Agree. It's essential to maintain consistency among different bindings.
