Now that internal dialect type is immutable, and the dialect registry
only contains instances of the dialect type, we can refer directly to the
dialect instances rather than creating new ones. In other words, if the
dialect comes from the registry, and we apply no further modifications,
the reader/writer can use the dialect object directly.
