Review Comment:
> I've introduced a new ConsumerAwareRebalanceListener
[here](https://github.com/apache/kafka/pull/22270/changes#diff-7b1d23741295e3d562a3da8f6e7378abbf4332b1c2766678f667d9840d119ce9R39)
That's not what I meant. What I'm proposing is a new public super-interface
for the end-users to implement. By extracting a public super-interface, we can
keep the new API completely clean for new users, while preserving 100% source
compatibility for legacy Scala users
