PIP-65 was implemented in #7090. @nlu90 @freeznet do you have any doc inputs for this PR?

//cc @Anonymitaet. May need to add a doc-required label to #7090.

@hsaputra thanks for rasing this up!

Adding a "how-to" doc for each interface is an unfeasible solution (e.g., adding a tutorial for every interface to https://pulsar.apache.org/docs/en/io-develop/) since it involves too much effort.

Instead, we show the usage of interfaces on the Java admin reference doc. If you want to know how to use the BatchSource interface, please check this reference doc. And I'll close this issue if there are no more concerns.
