But they do not intentionally limit support to other stuff. These are people working for their own pleasure, creating stuff that they need. They are not a company which creates stuff for money and needs to cater to its (spoiled?) users.

Users of this software are the developers themselves, and and anyone else who is pleased with the creation. And, for free!

You can even change the creation to your own liking, so, if you need a Windows build, why you don't step in?
