Yes then and yes now.It's interesting to note how differently this poll is going (so far) from as similar one from 4 years ago: http://www.enworld.org/forum/general-rpg-discussion/174075-good-idea-pull-lever-dungeon.html

A crafty trapsmith would trap the hallway since the rogue would look for traps in the room. =)
Or the crafty trapsmith would trap the ceiling to collapse as soon as you hammer in the piton, thereby burying the person and making the door inaccessible behind a wall of rubble. Oh, and pulling the chain just opens the door for those who know or aren't paranoid adventurers trying to steal his stuff.
Well yes of COURSE the chain gets pulled, but...You’ve finished off your objective in this dungeon, but your mapper points out an area in the back corner of the complex that your group never checked. Going there, you find a room empty except for a pull-chain hanging from the ceiling. You search the room and find a secret door in one wall. You can’t find a way to open the door. The rogue searches the door and the chain for traps, and finds none.
