`MKV_IS_ID` is a macro to check whether the object hiding behind a pointer has a certain dynamic type and it is being used all over the module. There are however a lot of cases that is followed by a static_cast to the appropriate type; `MKV_CHECKED_PTR_DECL` has been introduced to shorten code that has such usage.
