Elevators have had basically the same UI for decades. Most people don't even realize it could be different.
I've encountered residential buildings where you needed your key to select the correct floor. It meant you had to go down to the front door to let someone in, which was probably inconvenient.
There is another trend in office buildings: select the floor you want from a panel in the vestibule and it will tell you which elevator to get in to. At least this one is a little more common and people do quickly learn it. But it's still a UI change...
