No dice - if you think there's a possible conflict it's incumbent upon
you to alter your course, not to tell someone else to get out of your way.

I can see it now... There's the leader up ahead and it looks like he's
climbing. I'll transmit, "9B, turn right immediately for collision
avoidance!" There now... I'll just move into the thermal he's just
vacated. Gee, look how quickly I can overtake him.

The second paragraph is obviously for comic relief to this interminable
squabble.

Ideally you'd like ID available at minimum for traffic with an active alarm so you can say "9B turn right" at a safe distance. Relative altitude data allows some sense of climb rate - with a little math.
