Thank you for your comment. In my opinion, the use cases are a bit different.

Fill-mask capabilities are not the same as looking up words by their description. [Although you might adapt it to fill the placeholder straight away. But that is a different tool]

Also, I think what you are saying about 'it does not need email' is *not* entirely correct. HuggingFace requires you to log in once you reach the rate limit (and do not want to wait to run further queries)
