I'm trying to migrate a project which uses ficus to Scala3. I'm getting a compile-time error:

[error] -- [E008] Not Found Error: /Users/bwbecker/uw/cs135/scala/lintR/src/main/scala/cs135/config/Config.scala:9:33 
[error] 9 |import net.ceedubs.ficus.readers.ArbitraryTypeReader._
[error]   |       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
[error]   |value ArbitraryTypeReader is not a member of net.ceedubs.ficus.readers, but could be made available as an extension method.

I see that ficus/src/main/scala-3/net/ceedubs/ficus/readers/ArbitraryTypeReader.scala is only four lines long, one of which is //TODO. So I'm guessing that ficus isn't really ready for Scala3 even though there is a Scala3 release on Maven.

Can someone confirm or provide guidance on how to proceed?
