That is just Unreal Engine in general, UnrealScript just exposed the C++ classes. But UE's C++ classes have very deep hierarchies even in UE5 and many classes have tons of methods.
In general UE often feels like its programmers took all the best practices and then ignored every single one of them - which, considering how popular the engine is and for how long it had been around (the codebase started in the early/mid-90s), is a good indicator how much that stuff actually matter in practice.
