I'm surprised that scalafmt made such a breaking change. Maybe it's time to discuss Kyuubi 2.0, and we can consider including this change in 2.0 and keeping the existing behavior on 1.x serials.

I agree. This PR is more about a demonstration for the impact of scalafmt 3.8, which is no hurry to be merged for now.
