My intention for opening FLINK-8217 was more towards the purpose of clearly
identifying what is `@Internal` and should not be used. I can agree with that
we at least separate APIs to be annotated as either `@Internal` or
`@PublicEvolving` for now. Whether or not we want to elevate certain APIs to
`@Public` can probably be a separate issue.
