Feature Request

Q A
New Feature yes

Summary

Reading the documentation here: https://www.doctrine-project.org/projects/doctrine-orm/en/2.17/reference/working-with-objects.html#join-table-management-when-removing-from-many-to-many-collections

It seems the lookup on the JoinColumn for the onDelete="CASCADE" property is only done on the owning side of the many-to-many. It would be nice to get this working on the inverse side as well by looking it up via the InverseJoinColumn attribute. Means we can save an extra query and let the database do the cascade. Not sure how possible this is as the attribute lives on the owning target class.
