>   immutable data both with its callees within a thread, and with child
>   threads.  Scoped values are easier to reason about than thread-local
>   variables.  They also have lower space and time costs, especially
>   when used together with virtual threads (JEP444) and structured
>   concurrency (JEP480).  This is a preview API.

> then satisfactorily answered, then per the JEP 2.0 process proposal [2]
> I’ll target this JEP to JDK 23.

Hearing no objections, I’ve targeted this JEP to JDK 23.
