I think those scenarios are exactly where feedback could be valuable to the candidate. If the panel didn't feel the love, why so? If I get a low score on a coding test I am already going to realise that its going badly right there in the test so feedback is less valuable.

In my experience, it's either hard to articulate or it's something I wouldn't say to them like "you came across as very arrogant." Not the same thing but imagine dating scenarios. I've had plenty of situations where there were no red flags and also I couldn't have filled out a questionnaire about why I didn't "click" with a person.

That's not always the case. "Your writing sample was poor" so take a writing class. But I'd say that has been the minority and I could name one mistake where I assumed that was a flaw we could fix.
