@eevee meanwhile, I'm over here contributing to an open source Touhou fan game that prioritizes Linux so hard that we compile for Windows *on Linux* (using llvm-mingw)
it is a horrific hassle to do so but it's the principle of the thing. also honestly we probably couldn't do it with Windows's native tools at this point
we still have issues with older versions of Linux due to libc minimum version compatibility though, so minimum platform targets remain a thing. we have a whole workflow on Open Build System for various Linux distros and package managers but it's been years since we looked at it and bitrot is a serious concern at this point
