Given where things stood at Java 21 time and where we are now, can we move the idea of ephemeral thread support forward? This is very important to us and we are happy to get involved with the process and contribute if that would be helpful.
The possibility of GC'ing a started thread before it terminates is a scary topic. It interacts with many areas and gets really scary once you bring phantom refs, cleaners, and finalizers into the discussion.
For these so-called "forgotten sender" and "abandoned receiver" cases then it might be more interesting to see how they could be work with structured concurrency. Right now, the first API is focused on fan-out scenarios but in time we would like to have it work with channel like constructs too. I suspect this will be closer to what you are interested in.
