As part of the efforts to release Scala 3, we are about to change the naming schema of the Dotty artefacts. The artefacts will feature “scala3” instead of “dotty” thus moving us a step closer to the release of Scala 3.
The change will impact existing tooling that depends on the artefact names. Hence, once the change is done, the tool maintainers should adjust the tools accordingly. You can read more about the change in the blog article: https://dotty.epfl.ch/blog/2020/09/21/naming-schema-change.html
We depend on the Scala 2 standard library for binary compatibility, but we also have our own addition the standard library currently named dotty-library, we can’t rename it to scala-library and still depend on the Scala 2 scala-library.
Of course, you would need to do it with a next 2.x release. I don’t know if it is really an issue to update not only the version but also the group identifier. If it is an issue, then you most likely break all tools once you switch the artifact from scala3 to scala4, from 4 to 5 etc. and I don’t see why we should break things for every major release.
