Nope, that some people (points at self) like achievement systems. I guess they could learn that from MS too... but nope, they haven't from either of them so

I hope they never do.

Why not? It's a feature many people love and want (like me) and you don't ever have to look at them or anything. I don't see any downsides in it at all.
