The one thing where you need NOTIFY or BINDABLE is if you want to expose a class as a type to QML AND you want to make its instances usable in bindings; I believe that's where the warning originates from. However, that's not your use-case, so it shouldn't matter.
Value types do not need signals or bindables on their properties, even when exposed to QML. Since value types can only be held in properties of object types (possibly via multiple nested value types), there is always an object property the signal of which is used to notify about changes in the value type properties.
