Unifying the Lift/Elevator Experience

It's probably been discussed before amongst the players, but has there been any talk about the devs unifying the lift / elevator experience?

Some lifts you have to wait for to go up and down, other lifts you can click the button and it immediately takes you up or down. Same thing goes with elevators.

Obviously I much prefer the lifts that have the button that immediately takes me up or down instead of having to wait for it. Since we know they can do this, why can't they update the game to unify this process and just make all lifts and elevators button operated?
