Okay, this was just too intriguing so I nagged someone with Windows and
only the test for 204 fails there. So they actually block the other
ones. I don't really know about other 200'ds though, because I didn't
write tests for those there.

So yes, it seems like 2/3 allow 204. And GitHub is no small site.
Although what a strange thing of them to do.
