That's a bad choice (like go), but you can't expect people to find a unique name. It's best to avoid frequent words, names of popular things, and names in the same domain, for your project's visibility, but the dictionary isn't big enough for all the projects in the world. Github alone has over 200 million repositories.

That should only be an issue if projects have to be named with a preexisting word. But that practice will basically always end up conflicting with the existing meaning of the world. IMO the best names are words which previously didn't exists at all.
