It never occurred to me that it was a sort of censorship. I definitely think writers should be allowed to use it only at their discretion, since it's funny in some instances and not in others.
What's worse, though, is when a dramatic cartoon has to comment that "everyone survived" some sort of accident. Like in one of the Clock King episodes of BTAS (I forget which), there's a train crash, and moments later the mayor yells out "thank GOD everyone survived!" (or something to that effect). It stood out (in a bad way) because it didn't seem like the mayor could have possibly known, so soon after the crash, whether or not anyone was killed.
