> This ticket is a follow up to https://issues.apache.org/jira/browse/KAFKA-19668
> With K19668, we introduced some "hot fix", that is actually disabled by default for backward compatibility reasons. A cleaner fix (which required a KIP, and thus cannot go into a bug-fix release), would be to add a new overload of `processValues()` which has the fix enabled, and deprecate the existing `processValues()` methods.
