Doing so makes the Visual C compiler much less accepting of ill formed code, which will improve code quality on Windows in the future. It can be done with some effort, given that the significantly stricter gcc can now compile an experimental Windows JDK as of 2023, and will serve to significantly cut down on monstrosities in ancient Windows code
