/**
* This just unifies some logic that both [SqlResourceRepository] and [SqlDeliveryConfigRepository]
* need in order to construct resources and auto-migrate their specs to the latest version.
*
* Ideally I'd just make this a package-level function but since it requires collaborators it's
* easiest as a standalone class.
*
* Tests should test the behavior of the repository methods that use this class, rather than testing
* this class directly. This is just an implementation detail.
