Some of my experience of exams comes from a history degree where around eighty to ninety percent of the overall grade came from final exams. I can only speak of my experience but I don’t think this is atypical depending on educational system.

One of the reasons I mentioned the viva was an example of how we can decouple production of some work from an assessment of quality and some reason to believe that some candidate is capable of the work without assistance.

It would be unreasonable to spend five or so years working under examination conditions. But that doesn’t mean we can’t subsequently examine a candidate to determine likely authorship amongst other things.
