434	maybe i should introduce a new helper that returns a list of delete requests and call that helper from both `delete_otks_table_rows_for_user` and `delete_otks_table_rows_for_user_device`. my current implementation doesn't really use the batch write API efficiently

434	I don't think it's worth it. Delete user operation isn't something done often. Actually, one bigger batch of DeleteItem operations would be split into chunks of 25 so it wouldn't make a big difference.
