Hey Neil, I was taking a look at this code, and noticed that some unclean leader election params were not implemented. https://github.com/apache/kafka/blob/4612fe42af0df0a4c1affaf66c55d01eb6267ce3/metadata/src/main/java/org/apache/kafka/controller/ConfigurationControlManager.java#L499
I know you mentioned setting the non-topic config, but I wonder if the feature is generally not built out. I think that once KIP-966 is implemented, it will likely replace the old notion of unclean leader election. Still, if KRaft mode doesn't have unclean leader election, it should be documented. I will get back to you on this.
