It is way more valuable to me to tell me my keys or wallet just became separated from me and is now several feet away (while I'm away from home), than it is to try to lead me back to it at some unknown time in the future when I happen to realize I no longer have it.
Imagine being on the subway, getting up with your keys on the seat, you walk to the door as your stop is approaching and your iPhone tells you right then that you're separated from your keys.
Now imagine it doesn't tell you, what a difference that makes. I exit the train without my keys, walk 3 blocks to my building and only then do I realize my keys are gone. That train is headed north and God knows when or if I ever see them again and it's 10PM. That would really suck.
Or it leads me back to my wallet a few hours after losing it, only to find my cash and credit cards missing.
The iPhone always knows when the tag is close and would know immediately when that distance is increasing. Why not alert me? I can't think of any privacy or security reason for not doing this.
