Fans liked the idea, but no one said that it was a fan suggestion. I think it's far more likely that it was a garbled leak of the planned multiplayer that we're really getting, and possibly the Extended Cut as well. Some of the information we've been getting, like parts of Final Hours, suggest there were aspects of the ending that didn't make it in, such as a chance to actually ask the Catalyst questions - it's possible they were cut to get the game out and even the Extended Cut was planned all along.

So yeah, call me a pessimist, but I'm not seeing a lot of evidence that Bioware is responded to feedback here.
