I think I'd like to understand more about "Visual C++ no longer requires" - since when, how (un-)realistic is it that people would still be using a C++ compiler that would require the workaround, etc.

Because, as far as I know, the `JNIWriter` is used by users to generate the headers, and those users may be using various compilers, so I think we should verify we won't break the users.
