By this logic, why even have a wishlist?
The situation changes over time though.
Very, very rarely something original comes up in the wishlist that makes sense and has potential to be implemented. Off the top of my head, I can think of one major game change and a bunch of small features that have been added from the wishlist. I would say it was .0001% of what has been discussed on the wishlist forum. Might need a couple more zeroes before the 1 in there.
