People seem to think that things like this are worked on and completed overnight. These bouts of free time that a dev has could easily amount to something over a longer period of time. Small bits of free time, yet several years to slowly build it behind the scenes. It's doubtful that this flying in ARR zones was thought of just this expansion. If you had a small group of devs working together on this in their free time over the course of a few years, this could be accomplished. I doubt any resources were taken from anything just to complete this. Y'all love getting upset over QoL changes that don't directly affect you.
