This is a good report. I started a project last year on Scala 2.13, but had all Scala 3 compatibility features/warnings enabled from the beginning. It sounds like it should be an easy upgrade in the future as long as I don't rely on macros or libraries that rely on macros. I've tried to stick to libraries that already have Scala 3 releases or that come from plain Java.

It doesn't matter if libraries rely on macros because 1) you only depend on their compiled output and 2) you can use Scala 2.13 code from Scala 3. That said, the vast majority of the open source ecosystem has Scala 3 releases by now.

Is it recommended to start with Scala 2 instead of 3 right now?
