I wonder if it's dependant on whether the aiport has a radar feed or not. I
know that Ithaca does not, so may be requesting that you are clear. Airports
that either have there own radar, or have a feed from a nearby airport,
already know when you are clear.

That's interesting. Where I learned to fly (ITH), the tower controllers
routinely instructed pilots to "report clear of the Class D airspace."
Diff'rent strokes, I guess.
