In general embedded controllers like this don't have a lot of people working on them. They also have rules (enforced by review which isn't great) about when they can be accessed. In an embedded context you are not allowed to allocate memory (except at startup), so a lot of these globals are just arrays/buffers only used by one function or pseudo class (a class by intent but not actually a class by the language if the language even has a concept of class)
