It seems to me this eliminates one of the great advantages of Flarm - situational awareness. With a proper display you always know where the other gliders are around you, no need to wait for the alarm to take evasive action.

And you still have that same situational awareness for any planes near you. You just are not told who it is and how fast they are going up or down. The only thing lost is the ability to change where you go based on information about what the air is doing at some distance away from you.

So you get a glider symbol on the display with no contest number and no rate of climb? What about altitude? I have found the rate of climb indication pretty useless, too coarse and discontinuous to be of use for leeching. If you can see the glider you can better assess their relative climb by eye. But position and altitude are necessary for situational awareness.
