No open bug report for 4.2 so far, but I found an issue in the API doc: https://github.com/apache/spark/pull/56551 . The generated proto java classes and the new internal Types Framework ops classes are leaked into the Scala API doc.
Given we claim APIs in the API doc as public, I'm -1 to avoid releasing unexpected public APIs.
