> {{Reshuffle}} transform is a convenient wrapper around GBK. It preserves user
> windowing correctly which is not always obvious for users. It usage has grown
> over many months since it was deprecated as it makes it easier for potential
> incorrect/unportable use of GroupByKey semantics. See [dev
> thread|https://lists.apache.org/thread.html/820064a81c86a6d44f21f0d6c68ea3f46cec151e5e1a0b52eeed3fbf@%3Cdev.beam.apache.org%3E]
> for more discussion.

> There is a broad agreement we do need a transform that is meant for its
> common used purpose in user pipeline : to control parallelism (e.g. to
> control connections to a DB).
