   For now Scala 3 adoption is rather low (among other reasons - Akka HTTP is not released for _any_ version of Scala 3, and apparently it uses Scala 2 macros), so these updates wouldn't affect many people. Surely none that use Akka HTTP and would like to migrate to Pekko.
   
   According to the blog post - by the end of the year the compiler team want to release the first LTS version of Scala 3 (3.3). So the current situation is rather a temporary flux period before LTS kicks in. If 3.3 would be supported for at least 2 years as claimed, it would make sense to release Pekko for 3.3, stay on it until next LTS is adopted and then move on to next LTS.
   
   IMHO, moving fast _for now_ make sense. For many libraries blocker to update are macros and I notices that some important features stopped being `@experimental` only in 3.2.0, which would block importing certain functionalities before this version. And these libraries might slow down adoption for whole community, so I would expect for it to take off around the time that the compiler team want to release LTS, or even later.
   
   Once LTS program goes live this whole issue with upgrading should be solved. Pekko can just use the current LTS and maybe wait a bit when new LTS is released. That should give community enough time to bump their versions.
