I don't think affecting backports in general should be a reason to discourage new features from being used.

https://github.com/wenshao/jdk/commit/4a3da4b20fe0f7244c2c7bde3d9a0e2c8b91455a is great for me.

Implementing some functions of UUID in `Long` is inherently illogical. Now that we can implement it efficiently in the `UUID` class, there's no reason why we shouldn't.
