Hi all, does anyone have any data you can share on the size impact of converting JVM/Android libraries from Java to Kotlin? Working with a library team that is looking for good benchmarks on this.

OkHttp is the library that comes to mind for me of a successful rewrite story. It’s not quite as typical in that they required strict Java API and binary compatibility for their rewrite, and thus didn’t use Kotlin to its full potential. Here’s some stats for this rewrite
