I’m still undecided on what to think of this.
While there is great benefit in community driven processes there can also be some considerable drawbacks. I feel Jetbrains has kept, and continues to keep, the language very lean. It turned Kotlin into the pragmatic language it is today.
I wonder if a more community driven process will be able to maintain this pragmatic focus. The forum, slack channel and youtrack are full of new feature requests. Everybody is “missing” some feature from their favourite language, most notably from people with a Scala background. I fear that less influence from Jetbrains might turn Kotlin in another feature bloated language.
