==== Removal of domain object collection constructors

The following deprecated constructors were removed:

- DefaultNamedDomainObjectList(Class, Instantiator, Namer)
- DefaultNamedDomainObjectSet(Class, Instantiator)
- DefaultPolymorphicDomainObjectContainer(Class, Instantiator)

// and can create any number of equivalent Conns for use
// by multiple goroutines.
//
// A Connector can be passed to [database/sql.OpenDB], to allow drivers
// to implement their own [database/sql.DB] constructors, or returned by
// [DriverContext]'s OpenConnector method, to allow drivers
// access to context and to avoid repeated parsing of driver
// configuration.
