Part of the reason it has such high expectations is because they've basically never told us what it actually is. They've used some really vague language, which tends to lead to lots of speculation. Some of that could be translation too, but I don't think so.

Personally, I think they had something in mind then saw the reaction on top of people complaining about all the housing issues and are making changes to attempt to accommodate that in some capacity. I'd wager SE doesn't actually know what it is yet either.
