Being able to gauge a candidate's natural communication skills is highly useful. If you're an ineffective communicator, there's a good chance your comprehension skills are also deficient.
IMHO, an effective interview process should attempt to mimic the position for which a person is applying. Making a candidate jump through hoops is a bit disrespectful.
We are quickly moving into a world where most communications are at best assisted by AI and more often have little human input at all. There’s nothing inherently “wrong” about that (we all have opinions there), but “natural” (quotes to emphasize that they’re taught and not natural anyway) communication skills are going to be less and less common as time marches on, much like handwriting, typewriting, calligraphy, etc.
