CDG used to but I think we stopped using it when someone (pilot) taxied into it! I think MUC used to as well.
At JFK they have a hangar/building where you taxi in and it has infrared or such like lights in the ceiling and it melts all the ice/snow. Mind you never saw anyone use it.
hosser they are fixed structures, the idea being with short holdover times you could taxy through then lineup and go.
