Yes, but that seems sort of more OOC mechanical than anything else. If you can't tell, then you can't tell, regardless of if the bindstone tells you as a player...if you can tell (and I'm pretty sure everyone assumes you can), then you don't really need the big magic rock to tell you your soul has almost completely been ripped away, right?

Though I'm sure if it were supposed to be unknown in-character, it wouldn't be so readily available.
I wouldn't call it metagaming to have your character be aware of it though, no. I don't know if she would know "oh, I have lost eight soul strands out of ten" for example, but know that the tethers tying her to this world have been cut away to the point of barely existing, as Stephen said... why not?
