Review comment:
I think we should be way more explicit about this; scala users should
_never_ use `latest`; it is simply to easy to run into issues. If we release a
newer release, with scala 2.13 support we suddenly break everything.
I would explicitly phrase it like that; use it only if you are only using
java, otherwise select a specific Flink version with a matching scala version.
We should also look into providing a `latest_<scala.version>` tag to make
this easier for scala users.
