This is a low priority project for me - if some feels strongly about Scala 2 enums, feel free to have a look.

I never use Scala 2 enums for anything. Enumeratum and Scala3 enums - but never Scala 2 enums.

I'm not guaranteeing that even they work with collections but if they don't they are much easier to fix. Scala 2 enums are a real pain to use in swagger because of the way the type info is erased.
