Kotlin vs. Groovy for Gradle DSL

Hey gradle users!

In January 2020, how is the maturity of the Kotlin DSL?
Who’s using it in production? Has it been a good experience?
Are there any limitations or blind spots?

Is it as mature as the Groovy DSL?

P.S. There is a thread here, but it’s 3 years old, and I bet some things have changed.
