Hypothetically speaking, if Universal decides to close multiple attractions at once they would need the extra capacity to spread crowds. Here's the issue though: all the rumored/proposed closures (FFL, Shrek, KidZone) are all family/children experiences. Which is why I find it odd for Universal to open a HHN maze "for capacity" when it's not the intended audience. It could work as just a walkthrough without characters and just lights/effects on.
