Many libraries use Unsafe to improve performance, especially in many

Flink/Apache Arrow, etc. Direct removal will make it difficult to

It is recommended to use it similar to JEP 396, which needs to be
opened through parameters before it can be used and configured. The
JVM startup parameter "--illegal-unsafe=warn" can be enabled.
Removal should be after JDK 26.
This discussion is about the JDK's internal Unsafe, not sun.misc.Unsafe.
