Regarding the OP, you get a limited bit of altitude info when you can see dots, but no dar bar. So, above 65' and below 200' (?). Implementing a more detailed report on altitude would make offense even more difficult.
Now the reason why I am posting: How about a light on the dashboard that indicates if you are on radar? It would help over land NOEs immensely, when the altimeter is useless. Technically, radar is a radio signal that can be detected, so it is not magic.
For the "WIN TEH FITEZ" crowd, consider that the pendulum has swung from offense to defense. Base attacks are too often exercises in trying to climb above all of the other climbers.
