Honestly, I don't expect the all distro issues to be fixed/deployed in the field before JDK 25 GA and 25.0.1, so if we do this relaxation specifically for update releases, we would have to re-do it for JDK 25u.

The distros that are doing the in-place upgrades will need to change. Saying that JDK 25 will be less tolerant isn't a bad message, and it gives them a deadline to fix their issue.
