I think that before this PR is merged, it needs a wider discussion how to address the problem. Essentially allowing another producer to produce to the topic will break the guarantees of exclusive producers described in PIP-68, https://github.com/apache/pulsar/blob/master/pip/pip-68.md .

Please start a dev mailing list discussion so that this gets sufficient attention.
