It seems like it would be enormously helpful for requestor/reviewers to see at a glance the tasks that were converted from requests they raised. You can do this in custom reports or project filters (using "converted issue originator = me") but it does not work in the Home task widgets. The task widget only shows tasks that are assigned to the logged-in user, which only benefits Work license holders and not the vast majority of users with requestor/reviewer licenses.
I raised a support ticket on this; the rep was very helpful but confirmed the above and suggested I raise this as an idea.
