Support for Scala 3?

I am wondering if it is possible to publish a Scala 3 version of this library. I gave it a look today and found two obstacles:

  1. Slick still does not support Scala 3 and I would not bet money that it ever will. I could work around that with .cross(CrossVersion.for3Use2_13) but I am not sure if it is a good idea for a Scala 3 library to depend on a Scala 2.13 library.
  2. I guess the Scala 3 type checker is stricter, because I got a Type Mismatch Error in DatabaseProvider.scala:
[error] 21 |            val db: UIO[JdbcBackend#Database] = ZIO.effectTotal(d)
[error]    |                                                                ^
[error]    |                               Found:    (d : p.backend.DatabaseDef)
[error]    |                               Required: slick.jdbc.JdbcBackend#Database

Is there hope, or am I flogging a dead horse?
