There are upsides and down sides to this. First the cons, which is most likely what the dev team has already decided:
1. There are already 3rd party applications that can do this, therefore this would be a low priority request which amounts to a convenience feature.
2. Implementing this would require development and coding time that could be better spent elsewhere.
2a. Any such implementation would not be as robust as existing 3rd party applications, unless even more time and effort was spent on development.
3. Such a feature would require even more bandwidth and server power, either as a dedicated server separate from the game servers themselves, or as additional load on existing servers.
However,here's the pros (or rather, the arguments for):
1. Other popular mmo games have successfully implemented this feature.
2. The added convenience may attract more players to subscribe, if it becomes an sub-only or preferred-only feature (i'd go for the former). More subs=more money=feature pays for itself (eventually).
Actually, that's all I have on the pro side. Basically, while a welcome addition by many players, this amounts to a convenience feature which is already covered. I doubt Bioware would be willing to spend the $ in both dev cost and equipment/infrastructure requirements.
That said, I would be VERY pleased if Bioware proves me wrong on this one.
