> global variables are considered bad design

Global mutable variables, and they usually tend to be grouped into singletons (solving initialization issues, and fewer people bat an eye)

[RealityVoid]

Even global mutable variables are a problem only because they lend to spaghetti code and messy state handling if you use them in multiple places. But you could just... make a global variable and then handle it like you would a variable init with malloc. No functional issue there.
