Scala 2 and 3 are fundamentally the same language, which weakens the comparability to Perl5 => Perl6. The compiler is new and tooling will change but they do ensure Dotty can handle Scala 2 artifacts. Scala already doesn't offer binary compatibility between major releases, which in itself is a bit cumbersome but it allows them to innovate the compiler. So the change will not be as drastic as it might look. In addition, 2.14 is meant to be a release that eases the transition to Scala 3.
