"final" was an UnrealScript concept that never made it into Blueprints. Currently, it's synonymous with the CallParentFunction node. Instead of using this flag, we can simply check the node type directly. We still might want to revisit this for Blueprints, but we likely won't use this bool. #rb ben.hoffman, dan.oconnor [CL 30770789 by dave jones2 in ue5-main branch]
