These changes fix the following:
- Containers treat new values as new objects and make sure they're initialized.
- Fixed sized containers behave slightly different and will initialize all values when a new fixed sized container is created.
- Loading any values to a container will now return PartialDefaults instead of defaults used as adding any value to a container no longer makes the container a default as the default is always an empty container.
- The previous doesn't apply to fixed sized containers as those containers are always considered to have the exact number of values they can hold.
