   This is a good point. Another point is that Akka's Scala 3 support has so
   far been experimental and incomplete so expectations on compatibility are
   low. Until we make the first release, I think we should grant ourselves the
   flexibility of tracking the latest version of Scala 3. Not least, because
   Scala 3 has been somewhat unstable and we hit many regressions during the
   akka-http migration so we might have to take whatever works...
   
   Incidentally, Akka HTTP right now contains a copy of parboiled2 in its
   sources (with some slight additions). This decision was originally made on
   the grounds that Akka should not have many dependencies on Scala libraries,
   so it can be released quickly after a new (incompatible) Scala versions
   comes up. This point does not seem as important as before, so I'd suggest
   to move upstream parboiled2 when possible.
   
   I created https://github.com/apache/incubator-pekko-http/issues/1 to track
   this.
