Comment (by Olivier Dalang):
For reference, here's a package implementing this :
https://github.com/martinphellwig/django-query-signals
It includes also other bulk methods such as delete or bulk_create.
From the code, it looks like it suffers from edge case described above
(`the original queryset doesn't work for post_update, the update might
cause different instances to be returned than was updated, consider
qs.filter(deleted=False).update(deleted=True)`), but nothing unfixable it
seems.
