Ignored fields.  It includes many fields which are not generally honored.  For instance, ResourceVersion and FieldPath are both very rarely valid in actual usage. 2. Invalid usage help.  It is impossible to add specific help for individual usage.  In most embedded usages, there are particular restrictions like, \"must refer only to types A and B\" or \"UID not honored\" or \"name must be restricted\". Those cannot be well described when embedded. 3. Inconsistent validation.  Because the usages are different, the validation rules are different by usage, which makes it hard for users to predict what will happen. 4. The fields are both imprecise and overly precise.  Kind is not a precise mapping to a URL. This can produce ambiguity during interpretation and require a REST mapping.  In most cases, the dependency is on the group,resource tuple and the version of the actual struct is irrelevant. 5. We cannot easily change it.
