We have no `get_or_initialize`.  We'd have to move its definition into a generic `django_utils` class, and reference from SyncedModels and here.

Since this is preliminary code, I don't see the need to do all this.  Also, `django_utils` is refactored downstream, so I prefer not to touch it.

So I suggest leaving this as-is (perhaps with a comment), and think about changing it when we flesh out this functionality as we go.
