You capture the root issue quite well.

Now every tool has to adapt to Scala 3. And you guess it? It will take time. Even IntelliJ still doesn't correctly highlight syntax on some parts that also exist in Scala 2. And this has been years after Scala 3 was launched. It's mind-boggling.

They could have improved upon Scala 2 and incrementally add more capabilities. It's obvious they don't care about Scala's industry success. They care mostly about the academic success. Nothing wrong with that, but that should be made very clear.

In Scala, they have a huge debate with zealots arguing against, for example, early return; they would describe how bad it will be blah blah blah e.g. https://tpolecat.github.io/2014/05/09/return.html, meanwhile Kotlin supports early return with absolutely no issue.
