The GlobalConfiguration is explicitly passed around through constructors of various objects that need access to the configuration. This ad-hoc solution works for the specific use cases it was meant to support, but isn't very generic. We have a top-level object in libcamera, the CameraManager, that also needs to be accessed from various locations and is passed to object constructors. Standardize on passing the CameraManager everywhere, and access the global configuration through it.
