OK, "look like line noise to most humans".
The point is that they're a lot more cryptic, which I consider a feature, not a bug, for the reasons listed.

USNYC might be obvious; USPDX, perhaps not so much if you're not familiar with "PDX" for Portland, Oregon (and if USPDX *isn't* Portland, that might surprise a *number* of USans).

Yes, they *can*, but I don't know who other than Apple *have* done so already. Making the identifiers more cryptic might light a bit of a fire under more developers.

That's one of the cases I was thinking of (the other is Kolkata vs. Mumbai vs. Delhi).

"CH"? That's China, right? :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-)
(Yes, I know why "CH" was chosen for Switzerland. It's still probably not intuitively obvious to many that "CH" is Switzerland and "CN" is China.)
