So what do we do here? As I said, I really don't care for Windows as long as nobody in the team uses it.

And this:

 I wasn't able to test what happens in Windows because I couldn't get rake or rake reek to work on Windows (on the master branch without those changes).

is kind of a confirmation of my point. If we, the maintainers, can't even get the basic gem running on windows, why would we care about it? Open Source software always scratches your own itches, not the ones of others. That's what commercial software is for.

And right now this is blocking this, now isn't it?
