Unofficial is fine. It's also fine if the only way to use it is some unofficial or not-fully-supported thing, or if there are two ways but the unofficial one is better. It's just, if there's a real supported tool, it'd better not be possible to confuse with the unofficial one. If I were evaluating using a product like this and got confused about such a basic thing, I'd be gone.
