When enabling Editor Tracking on a Feature Class or Table, it would be nice if there were a checkbox or parameter that would also allow me to enable Editor Tracking on the Attachment Table for that Feature Class or Table.
This would allow me to look at the attachments and know who created an attachment and when. Additionally, if a user leveraged the Update Attachment rest endpoint on a Feature Service to update a given attachment, then that would allow me to know who changed/replaced an attachment.
