Comment:
https://docs.djangoproject.com/en/4.2/topics/db/queries/#topics-db-
queries-delete
As referred in the documentation,
{{{
Keep in mind that this will, whenever possible, be executed purely in SQL,
and so the delete() methods of individual object instances will not
necessarily be called during the process. If you’ve provided a custom
delete() method on a model class and want to ensure that it is called, you
will need to “manually” delete instances of that model (e.g., by iterating
over a QuerySet and calling delete() on each object individually) rather
than using the bulk delete() method of a QuerySet.
}}}
The current {{{delete()}}} method for a queryset already deletes objects
in bulk. Do we need another {{{bulk_update()}}} method for the same?
