The following JEP is proposed to target JDK 21:
446: Scoped Values (Preview)
Summary: Introduce scoped values, which enable the sharing of immutable
data within and across threads. They are preferred to thread-local
variables, especially when using large numbers of virtual threads.
This is a preview API.
Feedback on this proposal from JDK Project Committers and Reviewers 
is more than welcome, as are reasoned objections. If no such objections
are raised by 23:59 UTC on Tuesday, 6 June, or if they’re raised and
then satisfactorily answered, then per the JEP 2.0 process proposal 
I’ll target this JEP to JDK 21.
