I would say for the fairly big change like this, we want to wait until JDK 25 GA (that would pass the all-tests-run). It would be too late for Oct 2025 release, though. So realistically, this would target January 2026 release. You can pull this patch to your downstream JDK 21 to see if there are any troubles ahead of this path, this will also soothe 21u maintainer concerns, I think.
