They removed it because of an issue with games desyncing. The problem being that the HUD made it easier for people to see that their room is desynced, thus many people sending in tickets.
SDE's way of fixing the issue of to many people complaining about desyncs was to remove the easiest way to detect a desync.
No more complains = desync issue fixed :)
So, don't expect it to return. ever. ever ever ever. ever ever ever ever ever evevah evah evah ... ... evaaaar... again.
