Comment (by Sarah Boyce):

 I have been struggling to prove that the "pk" additions in `bulk_update`
 are required to prevent an  `OperationalError`. See
 [https://github.com/django/django/pull/19088 draft PR]
 This is also the only case I can find of `bulk_batch_size` with specific
 logic for handling primary keys

 If we agree these pk additions are not needed, then I think this is no
 longer a release blocking bug but rather a cleanup/optimization ticket.
