Maybe I misunderstood what I read? Maybe, there is an application that allows the fact the the alternative plaintext is gibberish to be ignored and compromise something?
Don't know if I got that correctly, but sabotaging a p2p network could be such an application. If a p2p network uses hashes to identify files, you could use this weakness to supply gibberish data (parts) to prevent successful downloads.
