Review comment:
That's why I would suggest to introduce `STRING` as early as possible such
that people start using it. We don't need to drop the old behavior immediately
but can do it maybe for Flink 2.0. This should have been discussed in FLIP-37.
Now it is documented and assumed at a couple of places.
