I asked about this the other day on Twitter and James pointed me to this SWTOR Q&A.

Unfortuantely, when they say it is "On the list" that just means it is a feature request. I would be a lot more interested in what priority they assigned to it. The fact that they mentioned that their attempt to implement it in beta caused performance issues tells me that the fix would touch a lot of code and likely is not trival. My gut feeling, as a developer myself, is that the risk probably outweighs the benefit and we are unlikely to see it until they overhaul the HeroEngine. Of course that is just an opinion that I hope is wrong.
