I think you might be goodhearting a bit (mistaking the measure for the goal) when you claim that final exam performance is productive. The actual product is the studying and prep for the exam, not the exam itself. The time limits and isolated environment is helpful in proctoring (it ensures the output is limited enough to be able to grade, and ensures that no outside sources are being used), not for productivity.
That’s not to say that these elements (isolation, concentration, time awareness, expectation of a grading/scoring rubric) aren’t important, just that they’re not necessarily sufficient nor directly convertible from an exam setting.
