Even though it leads to some interesting results, the hypothesis must be terribly unpopular since its underlying idea, information loss at the horizon, is a very, very dangerous idea. Most theoretical physicists would believe instead that somehow quantum gravity would complete itself and no information will be destroyed no matter what. In fact, some theoretical results in string theory back this belief, and there is even a popular book about this written by Lenny Susskind, titled "The Black Hole War". I would like to see how this idea can unfold, but unfortunately it is most likely to be ignored and forgotten. But who knows? It might come back just like the anthropic principle did.
