I only consider something an exploit only if it is game-breaking in some way. This game is full of undocumented features, so flipping out if someone takes advantage of one in game is silly even if the person maintaining the bug list considers it a bug (I mean, how many things on that list end up being WAD when the designers chime in).

Considering that the designers of the game have mentioned that they are OK with it, and its a not terribly effective tactic, it gets a pass in my book. I mean, the reason I play a computer game and not a tabletop game is so I don't have to argue rules with people. That means accepting all the little quirks in the game.
