Upon further investigation and discussion, this is actually the opposite direction from what we should be taking, and this direction wouldn't solve the motivational problem anyway. Additionally, some more (polly) tests have escaped being updated. So, let's just take a step back here. This reverts commitf3190dedee. This reverts commit749581d21f. This reverts commitf3df87d57e. This reverts commitab1dbcecd6.
