Forget it, you ain't gonna make Linux-centric open-source community to really care about Windows (or other un-POSIX-like OSes, of which today there is almost none). The others have to give in and accomodate to their ways if those others want to use their code.

And since Windows-centric developers, when porting their apps to Linux, are generally willing to accomodate for Linux-specific idiosyncrasies (that's what porting is about, after all) if they care abour that platform enough, the dynamic will generally stay the same: people porting from Windows to Linux will keep making compatibility shims, people porting from Linux to Windows will keep telling you "build it with MinGW or just run it in WSL2, idgaf".
