currently when a delete marker is deleted the event that is being sent is: s3:ObjectRemoved:Delete
this is confusing since the event has no "size" or "etag" since it does not refer to a specific version of the object.

instead, we suggest adding a new event type: s3:ObjectRemoved:DeleteMarkerDeleted and use in these cases
for this event, it would be expected that the size and etag values are empty.

• definition of types: https://github.com/ceph/ceph/blob/master/src/rgw/rgw_notify_event_type.cc
• and the code that set the value in the ops:
  https://github.com/ceph/ceph/blob/master/src/rgw/rgw_op.cc#L4786
  https://github.com/ceph/ceph/blob/master/src/rgw/rgw_op.cc#L6646

in the docs: https://github.com/ceph/ceph/blob/master/doc/radosgw/s3-notification-compatibility.rst

and would require adding a new test to verify this case:
https://github.com/ceph/ceph/blob/master/src/test/rgw/bucket_notification/test_bn.py#L1942

this is currently working with correct timestamp
please follow the instructions here to reproduce the delete marker deletion with notifications: https://gist.github.com/yuvalif/9bf24a6c2ccba7db62f8353156ab6a21

the event type for the delete marker deletion is "ObjectRemoved:Delete".
unless specifically requested, there is no intention of adding a new event type for the delete marker deletion case
