Does it make sense to use --show-error by itself in curl

I was trying to read up on it and just based off of the manual it seems not to make sense if I'm not using --silent alongside it, but I found this one article stating otherwise: https://nrogap.medium.com/show-error-response-for-curl-64666cd64330

I can't figure out if it's just AI slop or badly researched since it doesn't even show a real URL to test the commands against.
