It's one of the reasons, why I don't create PRs with massive replacements. I carefully choose places in the code, where I think replacement is 100% safe.
In this case we have a `final` field which has only 3 simple usages. Reviewing such small PR shouldn't take more than like 15 minutes.

Not sure I agree with this one. Even presence issues/PRs like this in JDK, could be used as an argument between developers, who need to choose what's better.
