The function IDENTITY does not hydrate customs types. I've a OrganizationId type, but when a execute the following DQL I got an error, because Doctrine tries to pass an integer as argument of my object constructor instead of an OrganizationId instance.

<mapped-superclass name="Campaign">
        <id name="id" column="id" type="campaign_id" />
        <id name="organization" column="organization_id" association-key="true" />
        <many-to-one field="organization" target-entity="Organization">
            <join-column name="organization_id" referenced-column-name="id" on-delete="CASCADE" on-update="CASCADE" />
        </many-to-one>
    </mapped-superclass>

SELECT NEW CampaignDTO(c.id, IDENTITY(c.organization), c.name) FROM Campaign c

Result:

Catchable Fatal Error: Argument 2 passed to Campaign::**construct() must be an instance of OrganizationId, integer given

This can now be fixed with TypedExpression support https://github.com/doctrine/orm/pull/7941

Identity should implement that interface and return the correct DBAL type of the column.
