This is still in the backlog but not scheduled at this time. I will provide an update if there is any movement on this idea.
We have released the first phase of task attachments. You can now add attachments to the Initial task emails. For more details, visit our community blog https://community.nintex.com/t5/Community-Blogs/Task-attachments-and-CC-BCC-Workflow-for-Office-365/ba-p/112529
In the next phase, we will add an option to include attachments for Reminder and Escalation emails.
