I agree with Enrico that we should revert this change in 2.11. BTW, I see https://github.com/apache/pulsar-client-go/pull/969 tried to upgrade the Pulsar version to 2.11 for Go client. I think we'd better skip this version. There is no need to upgrade the server version unless we have to add a new feature that depends on the new version of Pulsar.
