Hi all, I'm suggesting that we cherry-pick "PIP-428: Change TopicPoliciesService interface to fix consistency issues" (https://github.com/apache/pulsar/blob/master/pip/pip-428.md) to branch-4.0.
This is a breaking change for custom implementations of TopicPoliciesService on the broker side. Updating custom implementations to support the new interface is straightforward. Although breaking changes are discouraged, this change is necessary to fix the reliability and stability of topic policy updates as explained in the PIP document. PIP-428 has been implemented by PR https://github.com/apache/pulsar/pull/24427. I'll proceed with cherry-picking PR 24427 to branch-4.0 after 24 hours unless there are objections. -Lari
