Is support for Scala 3 planned?

Besides a very outdated [scala-3 branch](https://github.com/finagle/finch/tree/scala-3), I haven't found anything related to Scala 3. Can somebody give an authoritative answer to the question?

Start by reviewing the outdated scala-3 branch and the issue discussion to determine the project's current position on Scala 3. Done means documenting an authoritative answer about whether Scala 3 support is planned; the issue does not identify implementation files or tests.
