Shall reduce the scope of it. Let's leave launcher-package for later.

The only outstanding scripted test is stdlib-unfreeze, otherwise everything works for JDK 21.

Are there any standard library methods that are not in Scala Library 2.13.11 but are added later? As a part of the test checks whether sbt properly handles methods newly added to standard library for macro expansion.

Yes. Nothing public in the source code, but we've added things that are private[scala] or some subpackage. (And those are then public in bytecode, as expected.)

Thanks for the heads up. I guess we can do something similar to this to access these private methods.

And indeed after some searching, I found one such private method: scala/scala@8077afc
