You are thinking of something nice to have. At least half the idea here is that it would be nice not to have something.

Usually there are many buttons and links one wouldn't click on.

If authors can't resist having chunks of copy paste slop in the middle of their article they can do it in a way I don't have to see it.

They also get a fair opportunity to impress me with a prompt that looks interesting enough.

And they get to distance themselves from the idea that copying [say] a Wikipedia article into a blog posting is the same as writing something.
