You don't see gate numbers, simply because we haven't put it there...
The issue is: gate numbers at T5 are surely indicated on the jetways (as far I can gather from recent pictures), but we are not sure how they are and if they are also repeated on the actual building. Don't forget that, when we released JFK, T5 wasn't open yet!
Putting gate numbers on animated jetways can be very costly in performances, because an individual different model would be needed, just to differentiate them by the number, so that wasn't an option. And, missing any better documentation on the building, which surely wasn't available in any case when the scenery was in developement, we prefer not to "invent" anything, and simply don't put any numbers.
If anyone has updated pictures of T5, that would show if gate numbers are also on the building facade and in this case, how they look like, and would be so kind to send them to us, we might consider an upgrade.
