In the original FFXIV CE box art, there was some debate as to whether it was Siren or Garuda on the cover (if Siren, it would point to her being rather important). There was also some speculation then that she may have been the source of the Echo. Since we don't know what the original 1.0 plot was fully supposed to be, who knows if she once had a more important role in the story. The fact she has such a nice model seems to hint at such.
