@garyrussell, I can work on this. Could you please assign it to me?

[garyrussell]

Thanks!

We usually use @deprecated since 3.0 in favor of #setProducerInterceptor in the javadocs.

Now that we are on JDK 17, we can also set the since and for Removal attributes on @Deprecated

@garyrussell PR raised. Please have a look: #2225

Closing as invalid - the ProducerInterceptor does not have access to the outbound record.
