I am not sure if we need ​https://github.com/django/django/blob/master/django/db/models/deletion.py#L320-L323 (the block above) because I think field_updates is only ever filled if the objects are not fast-deletable -- ie ​https://github.com/django/django/blob/master/django/db/models/deletion.py#L224 is not called due to the can_fast_delete check at the beginning of the collect function. That said, if we want to be extra \"safe\" we can just move lines 320 - 326 into an extra function and call that from the old and new location (though I do not think it is needed).\n",
