"I wonder if they'd install an internal staircase (Does Building Code even allow a continuous internal volume that tall anymore? Maybe with automatic fire doors on each level.)"
Yup it does, at least in Alberta. Often you work it as a sort of interior atrium with smoke baffles, glass doors, or the like. Mechanically fire dampers can be used if needed.
