As far as I'm concerned though, that decreased the value of more advanced blocks like pistons, and opened up a whole bunch of sploity behavior. If I was more aware, or willing, at the time, I don't think I would have let that leak through to BTW in the first place.
IIRC, It was fence gates that didn't use redstone power when they were released; trapdoors always have.
Though there was an update in...1.9pre? can't remember, that bugged the whole thing out and caused them to update from a distance, which might be what you were thinking of.
