rogue ranged attack bonuses

I was looking around in old patch notes and came across this from a couple months before Kunark was released:

*Rogue Enhancements*

Rogues received several enhancements as part of this patch:

- The chance to score a critical hit with a throwing weapon has been
increased significantly.

- When throwing a weapon from behind the NPC in question, a rogue now
has a chance to score a "Deadly Strike", for enhanced damage above and
beyond that of a critical hit.

I was just wondering if these damage and crit bonuses already exist on this server or if they are planning on being implemented? I'm sure in practice it isn't that cool (hence why I never see rogues using throwing weapons in combat) but at least in theory it sounds awesome.
