   > what are the drawbacks if API Versions response uses the "uncommitted" 
kraft version?
   
   It's mainly a UX issue that impacts clusters undergoing a kraft version 
upgrade, or clusters who have not committed a "bootstrapped" kraft version 1 
yet (i.e. because of network partitioning). 
   
   The issue of exposing the uncommitted kraft version in the APIVersions 
response is that the finalized features level for kraft may be different 
depending on the node to which I send `APIVersionsRequest`. It also is not 
really "finalized." Metadata version also has this issue, which is being 
addressed as part of: https://github.com/apache/kafka/pull/21122
