I didn't know the ecosystem wasn't on 3.

It was released May 2021.

It is a big change though.

Most of the ecosystem is on Scala 3, I think Spark would be the biggest piece pending to upgrade.

With spark 4 defaulting to scala 2.13, that does move things in the right direction since the 2.13 -> 3 interop is possible
