I understand this. And that there is work entailed on the back end integrating a new system into an existing system. They still have the resources to easily manage such a change. They've had 3x financial resources for work on the new expansion over what they had for HW. The implementation of such a system.

Last I heard, Stormblood was twice the budget that Heavensward had, now it's suddenly triple that amount?

You'd also have to keep in mind that while they have a higher budget, that doesn't mean a system adjustment like this is high on priority, it's likely/hopefully being spent on more content at 4.0 launch. Avoiding another scenario where there isn't much to do at endgame is much higher on their priority list.
