As far as I know, there is no plan to allow instructors to "clear" exam attempts for students. It's easy to add an "extra attempt," and there is value to keeping a record of all exam attempts.
And, "clearing" the student's first exam attempt doesn't help with test security. If you make the answers immediately available, then the student could simply take screenshots after the first submission before you've had a chance to "clear" it.
Instead, just set up your Quizzes so that the correct answers are made available to your students at a later day and time after everyone has taken the Quiz.
