I was just talking to a friend about this, and we decided that it might also have been related to the difficulty of arranging more than one kick in a level... because you'd need two, right? One to bring everyone back to the level below (that was timed with the level below), and then one to get out and go to the level above (that was timed with the level above). Considering that these kicks also need to get everyone out at the same time, they tended to be something extreme, like blowing up the snow base, or (originally) blowing out the floor of the hotel room or driving a truck off a bridge. So it'd be hard to do them twice, even if you didn't have subconscious security to worry about and could take your time.
