Description
While looking at something different, we noticed a number of places where parameters did not have (non-scalar) type declarations, while they could have.
It would probably be a good idea to do a review of the complete codebase to add object-based/array type declarations wherever possible.
This would not be a breaking change as overloading methods not having a type declaration, means those are declared as mixed and mixed is contravariant with any type, so this would not lead to signature mismatch errors.
