Our decision now is to do it after because it will be more easy to see why it's necessary and we can take time to do them little by little. A new enhancement at https://bugs.openjdk.java.net/browse/JDK-8267432 is filed.

I just made it P3 (P4 was the default value), and I will target it to 17 once JEP 411 is targeted 17. But I think it's probably not a good idea to include it inside *this* PR. There are some middle ground where it's debatable if a change is worth doing (Ex: which is uglier between an a-liitle-faraway-annotation and a temporary variable?) so it's not obvious what the scope of the refactoring can be. Thus it will be divided into smaller sub-tasks. It's not totally impossible that part of the work will be delayed to next release.
