Notes: - For placeholder-typed objects, TObjectPtr<UObject> is considered to be type safe since placeholder types are based on UObject. - This means we can avoid having to check for and indirectly resolve placeholders via the ptr's internal object handle in these cases. #jira UE-209831 #rb Francis.Hurteau, Zousar.Shaker [CL 32434610 by phillip kavan in ue5-main branch]
