The other issue that you run into is that there are going to be a multitude of projects that are going to attempt this exact thing, which makes it a little tacky to just be the single person who's also running it as a live domain.
Just lifting the name of a product you're cloning to register a .clone TLD is simple, but it also inherently means that no one else can, and that's sort of problematic in the face of shipping something you're explicitly describing as a copy.
...or at least it would be if that were what had happened. I'm outside the edit window and would have noted it in the parent post otherwise, but may have misread this based on the title and not the repo -.-
