Yes, they are not dropping scripts completely, at least because of Gradle, but they are removing some parts of scripting support and advise against using Kotlin for scripting. And I would prefer a true command line REPL instead of the notebooks. IIRC they were promising various improvements in both scripting and REPL for several years, and now they just gave up, I guess because of shifting the focus to K2 and KMP. I find this quite disappointing.
