You're right, in that we would have said that.

I wouldn't frame it as moving the goalposts in a bad way, though. We understand more now than we did then, so we have a better idea of what the actual goal is, and moving the goalposts to frame that goal is more rational than insisting the goalposts stay where they were ten years ago even though the entire pitch has changed since then. I'm straining the analogy, obviously.
