The discussions are not very active now, due to various more important activities, but I hope to switch to the new scripting completely soon.
There will be some internal discussions, but I’ll try to organise as much public discussion around the KEEP as possible, and it seems to me that the KEEP issue
https://github.com/Kotlin/KEEP/issues/75 will be the main place for that.
And of course - you’re welcome to take a part. It is great that the kotlin scripting is in use now, and I hope we’ll make it better and simpler with that KEEP.
