Sadly, it makes sense to remove the statement, as it wasn't actually implemented in the patch.
Yes, but they usually don't have to remove anything from the patch notes if they can implement and/or fix any issues during a maintenance. Its removal signifies that they aren't trying to add it in anytime soon...or perhaps they had tried and failed. There is still a chance that the next patch will include it, but for now we'll have to cast it out of our minds. :/
